MHC Class I H2 Kd/Dd Mouse Monoclonal Antibody [Clone ID: 34-1-2S]

Specifications

Product Data
Clone Name	34-1-2S
Applications	FC, IHC
Recommend Dilution	Flow Cytometry: < / = 1 µg/10e6 cells. Immunohistochemistry (Acetone-Fixed, Frozen Tissue Sections).
Reactivity	Mouse
Host	Mouse
Clonality	Monoclonal
Immunogen	C3HalphaBDF1 mouse splenocytes.
Specificity	This antibody is specific to an epitope in the alpha 3 domain that is common to H-2Kd and H-2Dd. It binds to a common determinant in the alpha 3 domains of H-2Kd and H-2Dd in the presence or absence of beta 2 Microglobulin. (Ref.7,8) It cross reacts with the alpha 3 domain of H-2Kb. (Ref.1,2)
Formulation	PBS containing 0.09% Sodium Azide as preservative. Label: Biotin State: Liquid purified Ig fraction.
Concentration	lot specific
Conjugation	Biotin
Storage Condition	Store the antibody undiluted at 2-8°C for one month or in (aliquots) at -20°C for longer. This product is photosensitive and should be protected from light. Avoid repeated freezing and thawing.
Background	The 'classical' MHC Class I molecules are histocompatibility antigens encoded by the H-2 gene complex and consist of heterodimers of highly polymorphic alpha chains noncovalently associated with the invariant beta 2-Microglobulin. (Ref.3,4) These antigens are expressed on most nucleated cells but expression varies on different cell types. MHC Class I molecules present endogenously synthesized peptides to CD8+ T lymphocytes, which are usually cytotoxic T cells. (Ref.5) MHC Class I antigens expressed on thymic epithelial cells regulate the positive and negative selection of CD8+ T cells during T cell ontogeny. (Ref.3,6)
