Anti-Transforming Growth Factor beta (TGFb), clone 3H279

Transforming growth factor-beta (TGF-beta) family of proteins has potent hematopoietic regulatory properties ranging from effects on the growth and differentiation of primitive stem cells to the differentiated functions of mature cells. Applications: Suitable for use in Western Blot, ELISA, Neutralization and Immunohistochemistry. Other applications not tested, Recommended Dilution: Western Blot: 5-20ng/ml will allow visualization of 100ng/lane of TGF-beta. Recognizes the dimeric (25kD) and monomeric (12.5kD) forms of TGF-beta under non-reducing and reducing conditions, respectively., Neutralization: Neutralizes TGF-beta activity in vitro in an inhibition assay of CCL/64 cell growth and the growth promoting action of TGF-beta in the NRK-49F colony forming assay. The effect of microinjection of this antibody into one blastomere of two cell stage Xenopus embryos indicated that it was able to neutralize effectively the bioactivity of TGF-beta in vivo., Immunohistochemistry (formalin-fixed, paraffin-embedded, frozen): 1:1000. Has been used to demonstrate TGF-beta in ovine ovarian tissue and human breast carcinoma. As a consequence of the intense staining of the erythrocytes it is possible to locate a single cell within the ovarian stroma making it useful in locating very fine capillary networks within tissue. , Optimal dilutions to be determined by the researcher. Hybridoma: Sp2/0-Ag14 myeloma cells with spleen cells from Balb/c mice. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing.
