Vector Labs Ab00786-23.0 Anti-GM2 ganglioside [L55-81], Rabbit IgG, kappa (200 μg) Centrifuge Bundle Savings at Sycamore Life Sciences

Description

Product Class: Purified
Clone ID: L55-81
Amount: 200 μg
Application Codes Clone: ELISA; TLC; IHC; depleting
Shipping Temperature: Wet Ice
Origin Pub PMID: 9601948
Buffer Composition: PBS with 0.02% Proclin 300.
Original Format: IgM
Storage Temperature: Store at 4⁰C for up to 3 months. For longer storage, aliquot and store at -20⁰C.
Chimeric Use Statement: This chimeric rabbit antibody was made using the variable domain sequences of the original Human IgM format, for improved compatibility with existing reagents, assays and techniques.
Specificity Statement: L55-81 binds specifically to GM2 ganglioside; this antibody shows no reactivity towards GM1, GM3, GD2 or normal tissues- the L55-81 epitope contains both a GalNAc and sialic acid bound to lactose. Ganglioside GM2 (GalNAcβ1-4(NeuNAcα2-3)Galβ1-4Glcβ-1ceramide) is a glycosphingolipid present on the cell surface and a major tumor-differentiation antigen in human melanoma and hepatoma.
Application Notes: L55-81 reacts positively to melanoma cell lines with high GM2 expression (M14; M24), and shows no binding to normal cell types or cell lines M15 or M25 which have low GM2 expression and high GM3 expression. This specificity can be confirmed by ELISA and TLC immunostaining by testing a variety of gangliosides and neutral glycolipids. L55-81 is able to lyse cells from the M14 melanoma cell line (which has high GM2 expression) in the presence of human or rabbit complement, but not in the absence of complement - this was shown by a [51Cr] release assay. Biotinylated L55-81 has been used for IHC of acetone-fixed sections of tumor tissue in an avidin-biotin complex immunoperoxidase system. Statistically significant positive staining (determined by Fisher's exact test) was displayed with melanoma, colon carcinoma and ovary carcinoma tumor tissues. Staining has also be observed with breast carcinoma, prostate carcinoma and kidney carcinoma.
