Abstract
Defining HLA mismatch acceptability of organ transplant donors for sensitized recipients has traditionally been based on serologically defined HLA antigens. Now, however, it is well accepted that HLA antibodies specifically recognize a wide range of epitopes present on HLA antigens and that molecularly defined high resolution alleles corresponding to the same low resolution antigen can possess different epitope repertoires. Hence, determination of HLA compatibility at the allele level represents a more accurate approach to identify suitable donors for sensitized patients. This approach would offer opportunities for increased transplant rates and improved long term graft survivals.

Abstract
Twenty microsatellite markers have been typed on to the DogMap reference families, of which 18 were found to be polymorphic. One marker has been assigned to an existing linkage group and nine others have formed seven new linkage groups with previously typed markers. Only one of the new groups could be ordered.

Abstract
LMP2 is a subunit of the 20S proteasome within the cellular cytosolic compartment that is thought to cleave proteins into approximately 9 amino acid long oligopeptides. It is hypothesized that changes in the low molecular mass protease (LMP) gene sequence may alter the activity or specificity in which the LMP genes cleave peptides. Currently, the typing method for LMP2 involves polymerase chain reaction (PCR), restriction enzyme digestion, and gel electrophoresis. To help reduce the cost and cumbersomeness of this method, a new typing method was adapted for the LMP2 gene. To establish this new amplification refractory mutation system (ARMS) typing method, primers have been defined, amplification conditions optimized, and control cell lines sequenced to validate testing parameters. Results are listed for selected 10th and 11th International Histocompatibility Workshop homozygous cell lines.

Abstract
Protein concentration was determined, using the Bradford technique, in tears from cats with normal corneas and from cats with corneal sequestrum. Tears from the former group contained 5.81 +/- 2.29 mg of protein/ml; those from corneal sequestrum-affected cats contained 6.21 +/- 2.21 mg/ml. Difference between the 2 values was not significant. Molecular weight determination was made, using 4 to 20% sodium dodecyl sulfate-polyacrylamide gels. Molecular mass of proteins ranged from 263 to 14 kDa. There was no detectable difference in the band patterns for the 2 groups.
