Anti-Tenascin Antibody, clone DB7

Tenascin polypeptides isolated from spent culture supernatant of human fibroblasts isolated by affinity chromatography.

Detect Tenascin using this Anti-Tenascin Antibody, clone DB7 validated for use in IF, WB, IH(P).

Immunofluorescence: 1-2% PFA fixed, permeabilized tissues or cell cultures. Mild pepsin digestion improves staining.

Immunohistochemistry (formalin-fixed and paraffin-embedded sections): 1:200-1:400.

Requires pepsin digestion (0.1-.4% pepsin in .1% HCL pH 1.0, 30-50 minutes at 37C; neutralize sections with 2 quick rinses in 1X PBS pH 7.4 prior to blocking and antibody staining. Enhanced ABC or amplified detection systems recommended for best signals. See Soini, Y 1993 J Clin Patholo for protocol for decalified bone.

Immunoblotting: 1:1000; SDS sample buffer lysis of whole human fibroblasts; 6.5% PAGE reduced gels. Two distinct bands, 250,000 & 190,000 {Soini, Y Am. J. Clin. Path. 1993)

Final dilutions must be determined by end user.
