HLA Class 1 Antigen A3 (R0.90)
Description:
The human leukocyte antigen system (HLA) is the name of the major histocompatibility complex (MHC) in humans and is an essential element for immune function. This group of genes re- sides on chromosome 6, and encodes cell-surface antigen- presenting proteins and many other genes. Different classes have different functions: HLA class I antigens (A, B & C) present peptides from inside the cell, including viral peptides if present. These peptides are produced from digested proteins that are broken down in the proteasomes. Foreign antigens attract killer T-cells (also called CD8+ or cytotoxic T-cells) that destroy cells.

Applications:
Suitable for use in Cell Typing, Tissue Staining and Chimerism Studies. Other applications have not been tested.
Recommended Dilutions:
Cytotoxic Working Dilution: Add 0.9ml 1% BSA in PBS to 100ul of10X stock solution.
Optimal dilutions to be determined by the researcher.

Cytotoxicity:
Expected Results:
Cell death will occur in any test well where the HLA cell surface antigen is recognized by its matched anti-HLA antibody. Live lymphocytes indicate a negative reaction. Dead lymphocytes indicate a positive reaction.
Limitations:
Cell isolation difficulties, contamination of the lymphocyte preparation with red blood cells, monocytes, platelets or granulocytes, cell concentrations outside acceptable levels, bacterial contamination and/or change in pH of antisera may cause erroneous results.
