Western blot

Immunocytochemistry

Immunohistochemistry

Neutralization: 200ng of TNF-beta antibody is required for the neutralizaion of 1 unit/ml TNF-beta. The TNF-beta-preparation which is used has a specific activity of ca. 2x10(7) units/mg protein [cell lytic assay with L 929 cells (mouse transformed fibroblasts) and/or WEHJ 164 cells (mouse fibrosarcoma cells)/actinomycin D] .

Optimal working dilutions must be determined by end user.

This antibody is use for detection, identification and neutralixzation of TNF-b in cell culture and other biological samples. The antibody reacts with human natural and recombinant TNF-b (lymphotoxin). It does not react with human TNF-a. Determination of cross-reactivity to TNF-b from other species has not been done.

Format: Purified
