α-Gal Epitope (Galα1-3Galβ1-4GlcNAc-R), mAb (M86)



ALX-801-090-1	1 Vial	320.00 USD

Widely described antibody against α-galactose residues with broad cross-reactivity among different species. Useful for measuring the α-Gal epitope expression on cells, glycolipids and glycoproteins, characterization of hyperacute rejection (HAR) in organ and tissue transplantations and monitoring xenotransplantation experiments. The IgM isotype mimicks in vivo reactions and can be used for cytotoxicity assays for α-Gal specific pathways (addition or presence of complement necessary).

Formulation:	Liquid. Tissue culture supernatant.

Clone:	M86

Isotype:	Mouse IgM

Immunogen:	Rabbit red blood cell membrane.

Source/Host:	Hybridoma tissue culture.

Specificity:	Recognizes synthetic and naturally produced mouse, rat and pig Galα1-3Gal epitopes on glycoproteins and glycolipids. Does not cross-react with β-Gal glycoproteins or BSA.

Application:	ELISA Flow Cytometry Immunohistochemistry (paraffin sections) Western Blot Functional Application (can be used for cytotoxicity assays for α-Gal specific pathways) Note: Do not use non-fat milk for blocking! Many blocking agents from non-human mammal sources will cross-react with the antibody. Appropriate antibody dilution may vary from lot to lot. An initial dilution of 1:5 is recommended, if not otherwise indicated. Optimal conditions must be determined individually for each application.

Shipping:	SHIPPED ON BLUE ICE

Long Term Storage:	-20°C

Use/Stability:	Stable for at least 3 years when stored at -20°C.

Handling:	After opening, prepare aliquots and store at -20°C. Avoid freeze/thaw cycles.
