The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.

Quality Tested by Leinco Western Blotting: To detect Human NRG1-β1 this polyclonal antibody can be used at a concentration of 0.1-0.2 µg/ml. This polyclonal antibody should be used in conjunction with compatible second-step reagents such as PN:G505 and a chromogenic substrate such as PN:T343. The detection limit for Human NRG1-β1 is 2 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:N188. Each investigator should determine their own optimal working dilution for specific applications.

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. Background Neuregulin/Heregulin is a family of related growth factors that are differentially spliced variants of four genes: NRG1, NRG2, NRG3 and NRG4. The longest forms of NRG contains several different modular domains and tissue-specific splicing results in many NRG isoforms containing different sets of these domains. Alternative splicing produces two types of EGF domain, designated a and b. HRG-Beta1 contains an Ig domain and an EGF domain necessary for direct binding to receptor tyrosine kinases erbB-3 and erbB-4. HRG-Beta1 binding causes erbB-3 and erbB-4 to dimerize with erbB-2 (Her2/neu) and thereby regulates the phosphorylation of erbB-2 tyrosines. HRG-Beta1 stimulates proliferation and motility of breast cancer cells and plays a role in wound healing by stimulating epidermal migration and differentiation of epidermal cells and by stimulating the expression of integrins in the epidermis.
