Rat anti Rat MHC Class II I-Ab antibody, clone P7/7 recognizes the rat RT1Bu/Du MHC class II antigen and is cross reactive with haplotypes c, d, l, and n. The antibody positively stains MHC class II molecules in rat strains including PVG, F334, LEW, and BN.

Clone P7/7 also recognises mouse MHC Class II, binding to a monomorphic epitope expressed by all mouse strains.

Rat anti Rat MHC Class II I-Ab antibody, clone P7/7 has been used extensively in protocols used for the isolation of murine dendritic cells from mouse bone marrow by immunomagnetic depletion (Mölzer 2019, Siepmann 2007).

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
