CD74 (HLA Class II Histocompatibility Antigen gamma Chain, HLA-DR Antigens-associated Invariant Chain, Ia Antigen-associated Invariant Chain) (AP)

May be stored at 4 degree C before opening. DO NOT FREEZE! Stable at 4 degree C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months after receipt. 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.
