Abstract
Proteins and polypeptides are derivatized with dimethylaminoazobenzene isothiocyanate (DABITC) before their separation on sodium dodecyl sulfate-polyacrylamide gels. DABITC-derivatized proteins are detected visually in the picomole range without further staining and destaining procedures. The recovered colored protein can also be used for direct sequence determinations. This method was applied to purify heavy and light chains of murine hybridoma-derived antibodies. Starting with ammonium sulfate-precipitated protein mixture, this method allows, in a one-step procedure, the isolation of pure light and heavy chains suitable for automatic sequencing.

Abstract
The amino-terminal amino acid sequences of gp85 and gp37, the envelope glycoproteins of Rous sarcoma virus (RSV), were determined. Alignment of these sequences with the amino acid sequence predicted from the complete nucleotide sequence of the Prague strain of RSV, subgroup C (PR-C), has allowed us to delineate the env gene-coding region of this virus. The coding sequences for gp85 and gp37 have been placed in an open reading frame that extends from nucleotide 5045 to nucleotide 6862 and predict sizes of 341 amino acids (36,962 molecular weight) for gp85 and 198 amino acids (21,566 molecular weight) for gp37. Carbohydrate makes a significant contribution to the observed molecular weights of these polypeptides--the amino acid sequence contains 14 potential glycosylation sites (Asn-X-Ser/Thr) in gp85 and two in gp37. Experiments aimed at estimating the number of carbohydrate side chains yielded results consistent with most or all of these sites being occupied. Although an initiation codon is located early (codon 4) in the open reading frame, it is likely that splicing yields an mRNA on which translation initiates at the same AUG as that of the gag gene to produce a nascent polypeptide in which gp85 is preceded by a 62-amino-acid-long leader peptide. This leader contains the hydrophobic sequence (signal sequence) necessary for translocation across the endoplasmic reticulum and is completely removed from the env gene product during translation. The polyprotein precursor, Pr95env, is cleaved to gp85 and gp37 at the carboxyl side of the basic sequence:-Arg-Arg-Lys-Arg-. gp85 is attached through a disulphide linkage to gp37, and although the positions of the cysteines involved in this linkage are not known, the presence of a 27-amino-acid-long hydrophobic region at the carboxy-terminus of gp37 is consistent with its role as a membrane anchor for the viral glycoprotein complex. The location of host range variable regions with respect to the possible tertiary structure of the complex is discussed.

Abstract
The complete amino acid sequence of a proteinase inhibitor, eglin c (Mr 8100), has been determined with less than 150 micrograms of the protein using the following microtechniques: (a) amino acid analysis with a low-nanogram amount of protein hydrolysate using dimethylaminoazobenzene sulfonyl chloride, (b) peptide isolation at the picomole level using the dimethylaminoazobenzene isothiocyanate (DABITC) precolumn derivatization method, and (c) automatic Edman degradation. One amino acid residue has been corrected for the previously reported sequence. The Contribution of each technique to the microsequencing is discussed. In addition, a new high-performance liquid chromatography system that gives a complete baseline separation of all phenylthiohydantoin-amino acids is described.

Abstract
A method for electrophoretic elution of proteins from polyacrylamide gel slices is described. Eluted proteins were retained by a discontinuous conductivity gradient (M. Otto and M. Snejdárková, Anal. Biochem. 111, 111-114 (1981)). The method has been adapted to slices from slab gels and gels that have been stained and destained. Proteins were eluted as their sodium dodecyl sulfate complexes. Minute amounts of proteins (0.1 microgram) were recovered in high yield (85-95%) in 2 h in less than 0.1 ml volume.

Abstract
The hog sucrase-isomaltase complex is anchored to the small-intestinal brush border membrane, as in the rabbit, via a hydrophobic segment located in the N-terminal region of the isomaltase subunit. The immediate precursor of the 'final' sucrase-isomaltase (i.e., pro-sucrase-isomaltase as prepared from adult hogs whose pancreas had been disconnected from the duodenum) is an amphiphilic single polypeptide chain of Mr 260000-265000. Its N-terminal sequence is virtually identical with (not merely homologous to) the corresponding region of the isomaltase subunit of 'final' sucrase-isomaltase. This shows that the isomaltase portion of pro-sucrase-isomaltase is the N-terminal 'half' of the precursor polypeptide chain. Thus the succession of domains in pro-sucrase-isomaltase and its mode of anchoring in the membrane could be deduced. On this basis a likely mechanism of biosynthesis and insertion is proposed.

Abstract
Mouse monoclonal antibody directed against human leukocyte alpha interferon (IFN-alpha) was coupled to Sepharose and used as an immunoadsorbent to purify human IFN-alpha. Leukocyte and lymphoblastoid (Namalva) IFNs were retained by the immunoadsorbent with a specificity of 80 to 100% and 40 to 60%, respectively. Human IFN-beta or -gamma and mouse IFN were not retained. The purified IFN-alpha retained its antiviral and anticellular properties as well as its ability to induce the 2-5A synthetase in human cells with a specific activity similar to that of the crude IFN. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of radioactively labeled IFN showed that it consisted of several proteins in the molecular weight range of 17,000 to 27,000. 125I-labeled IFN-alpha with a high specific activity (2,000 Ci/mmol) was used in a radioimmunoassay for the titration of IFN-alpha.

Abstract
An approach to sequencing proteins by the solid-phase method combined with isolation of proteins and polypeptides by gel electrophoresis is described. Mixtures of proteins or polypeptides resulting from digests are fractionated in the presence of dodecylsulphate in polyacrylamide gels. They are detected with Coomassie blue, eluted, selectively reacted with porous glass derivatives and sequenced in their amino-terminal regions with the aid of a new microsequencer. Alternatively they can be analysed or digested with enzymes and fingerprinted. It is a relatively rapid method of purifying proteins for sequence analysis which we have used to provide partial protein sequence data to complement DNA sequences. Nine genes, four from the unc operon of Escherichia coli encoding the alpha, beta, gamma and epsilon subunits of ATP synthase and five for capsid proteins of bacteriophage lambda, have been identified by this method.

Abstract
Monoclonal immunoadsorbent chromatography has been used to isolate milligram quantities of detergent-solubilized H-2Kk antigen. Using the procedure described in this paper 10(12) cells may be processed yielding 10 mg of homogenous H-2Kk which represents 70% of the allotypic serological activity present in the original homogenate. NH2-Terminal sequence data of the first 30 residues of the H-2Kk heavy chain are presented. The cell line selected as the source of antigen and the criteria of purity of the antigen have been found to be critical as proteins of molecular weight 42,000 and 12,000 were copurified with H-2Kk from the BW5147 cell line. The additional components were observed in gradient gel electrophoresis or two-dimensional electrophoresis, but not in conventional Laemmli gel electrophoresis.

Abstract
Highly purified human factor B of the alternative complement pathway was treated with factor D in the presence of cobra venom factor to generate its Ba and Bb cleavage fragments. These cleavage fragments were isolated by preparative polyacrylamide gradient gel electrophoresis followed by electrodialysis elution and treatment with CNBr. The resultant CNBr cleavage peptides were isolated by molecular exclusion high performance liquid chromatography and characterized by SDS polyacrylamide gel electrophoresis. Results of these experiments indicate that the Ba fragment essentially consisted of a 28,000 CNBr peptide, whereas 34,700 (28,000 + 3,500 when characterized under reducing polyacrylamide gel electrophoresis conditions); 14,500 (=20,000); and 8,300 CNBr peptides were derived from the Bb fragment.

Abstract
Partial amino-terminal sequence analysis was performed on radiolabeled polio-virus capsid proteins VP1, VP2, and VP3. A computer-assisted comparison of the amino acid sequences obtained with that predicted by the nucleotide sequence of the poliovirus genome allows assignment of the amino terminus of each capsid protein to a unique position within the virus polyprotein. Sequence analysis of trypsin-digested VP4, which has a blocked amino terminus, demonstrates that VP4 is encoded at or very near to the amino terminus of the polyprotein. The gene order of the capsid proteins is VP4-VP2-VP3-VP1. Cleavage of VP0 to VP4 and VP2 is shown to occur between asparagine and serine, whereas the cleavages that separate VP2/VP3 and VP3/VP1 occur between glutamine and glycine residues. This finding supports the hypothesis that the cleavage of VP0, which occurs during virion morphogenesis, is distinct from the cleavages that separate functional regions of the polyprotein.

Abstract
A partial amino-terminal amino acid sequence of each of the major proteins encoded by the replicase region (P3) of the poliovirus genome has been determined. A comparison of this sequence information with the amino acid sequence predicted from the RNA sequence that has been determined for the 3' region of the poliovirus genome has allowed us to locate precisely the proteolytic cleavage sites at which the initial polyprotein is processed to create the poliovirus products P3-1b (NCVP1b), P3-2 (NCVP2), P3-4b (NCVP4b), and P3-7c (NCVP7c). For each of these products, as well as for the small genome-linked protein VPg, proteolytic cleavage occurs between a glutamine and a glycine residue to create the amino terminus of each protein. This result suggests that a single proteinase may be responsible for all of these cleavages. The sequence data also allow the precise positioning of the genome-linked protein VPg within the precursor P3-1b just proximal to the amino terminus of polypeptide P3-2.
