MHC Class 2, I-A

May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Recognizes a monomorphic determinant of the rat I-A antigen present on B lymphocytes, dendritic cells, some macrophages and certain epithelial cells. Crossreacts with certain mouse strains of MHC haplotypes k and s and analysis of recombinant strains showed that the determinants mapped to the I-A region of the mouse MHC. Species Crossreactivity: Mouse. Does not recognize BDIX rat strain.
