MHC Class 1, H2, Dd (PE)

May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20 °C or colder. Aliquots are stable for at least 6 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.

Reacts with a conformational epitope on H-2Dd MHC Class I found on the N-terminal domains of alpha1 and alpha2 chains when complexed with b2-microglobulin. Does not react with H-2Dd alpha chains synthesized in vitro. Weak cross-reactivity with cells from mice of the H-2b, H-2q, and H-2s haplotypes has been observed by flow cytometric analysis. Reactivity with cells from mice of the H-2f, H-2k, H-2p, and H-2r haplotypes has not been observed. Has been reported to block the recognition of H-2Dd by Ly-49A+, Ly-49C+, and Ly-49G2+ natural killer cells.
