TGF alpha IHC

Immunohistochemical analysis of TGF alpha expression in FFPE rat colon tissue.  

Cat#RPA01135 was used as primary antibody dilution 1:500, DAB chromogen substrate.

Polyclonal TGF-alpha antibody was produced from sera of rabbits  immunized with synthetic protein containing TGF-alpha antigenic determinants. 
Species reactivity:

Serum IgG fraction was purified by Protein G affinity chromatography.

Lyophilized from sterile filtered PBS solution at a concentration of 1mg/ml.
A quick spin of the vial followed by reconstitution in distilled water. This solution can then be diluted into other buffers
The lyophilized antibody is stable for at least 1 year  from date of receipt at -20° C.
Upon reconstitution, this antibody can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months without detectable loss of activity.

Avoid repeated freeze/thaw cycles.

TGF-alpha is produced by a number of human carcinomas and cell lines transformed by viral and cellular Oncogene.The production of TGF-alpha in pituitary cells in inhibited by TGF-beta. TGF-alpha is produced by keratinocytes, macrophages, hepatocytes, platelets. Its synthesis is stimulated by infection with viruses. In mammary tissue its synthesis is induced by estrogens. The protein has a length of 50 amino acids. It is not related to TGF-beta. The factor is obtained by proteolytic processing of a transmembrane precursor protein of 160 amino acids. Membrane-associated elastase-like serine proteases have been implicated in the processing of the pro-TGF-alpha form. Rat and murine TGF-alpha are almost identical with the human factor. TGF-alpha is related closely to EGF and TGF-alpha is therefore sometimes called EGF-like transforming growth factor. The biological activities of these two growth factors are very similar and both bind to the same receptor. The transmembrane precursor of TGF-alpha can bind to EGF receptors on near-by cells. This enables it to establish specific cell-to-cell contacts and to elicit developmentally important responses in neighboring cells.
