Specifications

Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IH FC N
TGF-b1, -2 and -3 are a closely related group of proteins (70-80% sequence homology) that are produced by many cell types and function as growth and differentiation factors. The active forms of TGF-b1, -2 and -3 are disulfide-linked homodimers.
Catalog #T8250-16
ApplicationsSuitable for use in Capture ELISA, Neutralization, Western Blot, Flow Cytometry and Immunohistochemistry. Other applications not tested.
Recommended DilutionsCapture ELISA: 2-8ug/ml. Can be paired with T8250-16B (0.1-0.4ug/ml) as the detection antibody in sandwich ELISA.
Neutralization: 0.3-1ug/ml will neutralize 50% of the bioactivity in the presence of 0.25ng/ml of recombinant human TGFb1 and 7.5ng/ml recombinant mouse IL-4. Measured by its ability to neutralize TGF-b1 inhibition of IL-4 dependent proliferation in the HT-2 mouse T cell line.
Western Blot: 1ug/ml. Reducing conditions are not recommended.
Flow Cytometry (Intracellular): 2.5ug/ml labels 1x10e6 cells. Validated using PC-3 human prostate cancer cell line fixed with paraformaldehyde and permeablized with saporin.
Immunohistochemistry: 8-25ug/ml in immersion fixed paraffin embedded sections of human prostate cancer tissue.
Optimal dilutions to be determined by the researcher.
Recommended Secondary AntibodiesI1904-06F: IgG, H&L (FITC) (X-Adsorbed) Pab Gt x Mo
I1904-23: IgG, X-Adsorbed (DTAF) Pab Gt x Mo

ImmunogenRecombinant protein corresponding to human transforming growth factor beta 1 (TGF-b1) and latent TGF-b1 expressed in CHO cells (P01137).
SpecificityRecognizes human TGF-b1 both in its active form and in its latent form when it is complexed with LAP (latency associated peptide.). Neutralizes the biological activity of TGF-b1 and TGF-b1.2.
Species CrossreactivityMouse and rat. In sandwich ELISA, <2% crossreactivity with recombinant human TGF-b3 and recombinant amphibian TGF-b5 was observed and no crossreactivity with recombinant porcine or recombinant human TGFb2 was observed.
