Abstract
A series of 6 hybrid clones are described which produced antibodies directed to murine IgM. These were derived by immunizing rats with W279 B-lymphoma cells and then fusing the immune spleen cells to enzyme-deficient murine plasmacytoma cell lines. Immunoenzymatic techniques were used to select clones producing desirable antibodies to cell surface or soluble antigens. Antibodies from 3 of the clones (293.14, 414.18 and 307.5) preferentially bound to idiotypic determinants of W279 immunoglobulin whereas the remaining 3 clones made antibodies which bound to various myeloma and normal cell surface IgM molecules. One IgM-specific clone (287.2) produced antibody of relatively low avidity. The two other clones (81.20 and 331.12) which secreted anti-mu antibodies appeared to be directed to determinants which differed in glutaraldehyde lability and expression in F(ab')2 preparations.

Abstract
We evaluated the performance characteristics of the Beckman Creatinine Analyzer 2, a kinetic colorimetric analyzer which utilizes a modified Jaffé reagent. The instrument gave linear measurements to at least 300 mg/L and its within-run precision on a 50 mg/l creatinine standard was 1.1%. Its between-day precision on the 50 mg/L creatinine standard was less than 5.0%. Its results correlated well with those from the manual Jaffé. CentrifiChem System 400, TechniconTM SMATM 6/60 System, and TraceTM systems I and III. Interferences from 19 possible serum constituents and 32 drugs were almost nonexistent. The extended linear range of the Creatinine Analyzer 2 allowed the direct assay of samples from patients undergoing periodic hemodialysis.

Abstract
Five gibbon ape leukemia virus substrains (two from gibbons with lymphocytic leukemia and three from gibbons with myelogenous leukemia) were examined for unique genomic sequences specific for each form of leukemia. By using sequential adsorption procedures, the genome from each gibbon ape leukemia virus was fractionated into four sets of distinct nucleotide sequences. Based on their hybridization specificities toward DNAs of leukemic tissues, these sequences were designated as follows: (i) "COM," (ii) "LYM" or "MYE," (iii) "UNI," and (iv) "UND." The COM fraction represented sequences common to all of the viral genomes. The LYM fraction, which was isolated only from gibbon ape leukemia viruses associated with lymphocytic leukemia, represented genomic sequences associated with lymphocytic leukemia since the RNA hybridized at a 4- to 15-fold-higher rate to infected tissue DNA from lymphocytic leukemic gibbons than to infected tissue DNA from myelogenous leukemic gibbons. The MYE fraction, which was isolated only from gibbon ape leukemia viruses associated with myelogenous leukemia, represented genomic sequences associated with myelogenous leukemia since the RNA hybridized at a 5- to 15-fold-higher rate to infected tissue DNA from myelogenous leukemic gibbons than to infected tissue DNA from lymphocytic leukemic gibbons. The UNI fraction contained sequences unique to one virus substrain. The UND fraction contained sequences which varied depending upon the substrains involved in the adsorption procedures. These findings suggest that each gibbon ape leukemia virus examined in this study contains subgenomic sequences that are specifically identifiable only with the form of leukemia from which the virus was isolated.

Abstract
An immunoprecipitation assay for measuring synthesis of murine terminal deoxynucleotidyltransferase (EC 2.7.7.31) has been developed using rabbit antiserum to calf terminal transferase. The antiserum precipitates a single Mr = 60,000 polypeptide (TdT-60) from all cell lines and tissues that contain enzymologically demonstrable terminal transferase. This polypeptide is not precipitated from labeled extracts of cells that lack terminal transferase by enzymological criteria. TdT-60 fractionates with terminal transferase during phosphocellulose chromatography and sediments with it in a sucrose gradient. TdT-60 is not detectably processed to lower molecular weight polypeptides, and terminal transferase activity sediments as a Mr = 60,000 activity; thus, we believe it to be the active form of terminal transferase. Using this assay we have demonstrated that terminal transferase is synthesized in both the murine thymus and the bone marrow at a rate proportional to its biochemically measured steady state level. After cortisone treatment of mice, the Mr = 60,000 polypeptide disappears from the thymus and then reappears as the thymus begins to be repopulated.

Abstract
The 70S RNAs from several gibbon type C viruses were examined for sequence homology by molecular hybridization using complementary DNA probes. The sequence homology was found to vary with each virus isolate. The genome from one isolate was examined for genomic stability after the virus was experimentally passaged through three unrelated gibbons. The genomic homology remained unchanged after three passages, having greater than 93% homology based on complementary DNA-70S RNA hybridization and melting temperature analysis of the duplex. The genome from another isolate was similarly found to be unchanged after the virus was naturally transmitted in gibbons. The genomic variation found in the various isolates is not the consequence of recent horizontal transmission from a common virus.

Abstract
Gibbon leukemia virus can infect prenatal gibbons through in utero infection or postnatal gibbons through contact transmission. The transmission of infectious virus was from viremic gibbons and not from uninfected or antibody-positive animals. The two modes of transmission could be distinguished by the amount of proviral DNA integrated into the muscle tissue of viremic gibbons. Muscle of gibbons infected postnatally had little or no proviral DNA, whereas gibbons infected prenatally had a large quantity of proviral DNA.

Abstract
Patients' sera were analyzed for carbamazepine and ethosuximide by enzyme immunoassay (x) and gas chromatography (y), and the results were compared. The correlation coefficients were: for carbamazepine, x vs. y 0.94 (n = 93); for ethosuximide, x vs. y 0.99 (n = 30). These results suggest that the two methods could be used interchangeably. Ten serum samples supplemented with carbamazepine (2.5 to 12.5 mg/liter) and ethosuximide (20.0 to 130.0 mg/liter) were analyzed by both methods. The correlation coefficients were: x vs. y 0.99 (n = 10) for carbamazepine and x vs. y 0.99 (n =10) for ethosuximide.

Abstract
Upon ethyl nitrosourea treatment of RNA of tobacco mosaic virus, up to four phosphodiester groups may be alkylated per molecule without chain breakage, as shown be sucrose gradient centrifugation. This indicates that ribophosphotriesters are quite stable. However, when this alkylation reaction is of longer duration and 6 to 10 triesters are formed, then an average of 1 to 2 breaks occurs and little or no intact RNA can be isolated. Methyl nitrosourea is less effective in forming triesters (about 25% of total alkyl groups compared to about 65% for ethyl nitrosourea), and a greater number of alkyl groups can, therefore, be introduced before breaks occur. Diethyl sulfate and dimethyl sulfate, which alkylate almost only the bases of nucleic acids, do not cause significant degradation of RNA of tobacco mosaic virus, even when as many as 70 alkyl groups are bound. All types of alkylation cause similar losses in viral infectivity at low levels of alkylation. Thus, an average of two chemical events leads to one lethal event, regardless of the nature of the alkylating reaction, which, for example, is with dimethyl sulfate about 65% on the N-7 guanine while with ethyl nitrosourea it is about 65% on phosphodiesters. It is thus concluded that all alkyl groups, whether on the base or on the phosphate, have the same potential to cause inactivation and that inactivation of RNA can result from phosphotriester formation per se.

Abstract
The sites and extent of ethyl products of neutral ethylation of HeLa cell DNA by [14-C]diethyl sulfate, [14-C]ethyl methanesulfonate, and [14-C]ethylnitrosourea have been determined in vitro and in vivo, and found to differ significantly depending on the ethylating agents. Diethyl sulfate and ethyl methanesulfonate ethylate the bases of HeLa cell DNA in the following order: 7-ethylguanine greater than 3-ethyladenine greater than 1-ethyladenine, 7-ethyladenine greater than 3-ethylguanine, 3-ethylcytosine, O-6-ethylguanine. Ethyl bases accounted for 84-87% of the total ethyl groups associated with HeLa cell DNA. Ethylnitrosourea, in contrast, has particular affinity for the O-6 position of guanine. It ethylates the bases of HeLa cell DNA in the following order: O-6-ethylguanine, 7-ethylguanine greater than 3-ethyladenine greater than 3-ethylguanine, 3-ethylthymine greater than 1-ethyladenine, 7-ethyladenine, 3-ethylcytosine. Ethylation of the bases only accounts for 30% of the total ethylation in the case of ethylnitrosourea. The remaining 70% of the [14-C]ethyl groups, introduced in vivo and in vitro, are in the form of phosphotriesters which after perchloric acid hydrolysis are found as [14-CA1ethanol and [14-C]ethyl phosphate. In contrast, phosphotriesters amounted to only 8-20% of total ethylation in in vivo or in vitro diethyl sulfate and ethyl methanesulfonate treated HeLa cell DNA, and 25% of the total methylation in in vitro methylnitrosourea treated HeLa cell DNA. Alkylation at the N-7 and N-3 positions of purines in DNA destabilizes the glycosidic linkages. Part of 7-ethylguanine and 3-ethyladenine are found to be spontaneously released during the ethylation reaction. Incorporation of the 14-C of the alkylating agents into normal DNA bases of HeLa cells can be eliminated by performing the alkylations, in the presence of cytosine arabinoside, for 1 hr.
