Purified Recombinant Human TGF-α (Accession # P01135)
This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.4 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.
Storage and Handling
The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted biotin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Western Blotting: To detect Human TGF-α this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as PN:A106 and a chromogenic substrate such as PN:T343. The detection limit for Human TGF-α is 25 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:T151.
ELISA Sandwich Assay: This antibody can be used as the detection antibody in a sandwich ELISA at a concentration of approximately 0.1-0.4 µg/ml when used in conjunction with PN:T145 as the capture antibody at 0.2-0.8 µg/ml and an optimal second step reagent such as PN:A106 for the detection of Human TGF-α.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Goat Anti-Human Transforming Growth Factor-Alpha (TGF-α) recognizes Human TGF-α. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
Transforming growth factor alpha (TGF-α) is thought to be the major autocrine factor controlling growth in epidermal cells.1 It plays an important role in cell proliferation during embryogenesis.2 It also stimulates neural cell proliferation in the adult injured brain.3 TGF-alpha is an oncogenic growth factor which drives estrogen independent breast tumor proliferation via an autocrine loop.4 TGF-alpha which normally suppresses tumours can actually be used by cancer cells to enhance their ability to spread. It is present in high levels in around half of all breast tumours, and these tumours tend to be more aggressive and more likely to spread to the lungs. It has been shown that TGF-alpha can prompt breast cancer cells to make another cytokine called angiopoietin-like 4 (ANGPTL4), which helps the cells to spread through the bloodstream.5
