Product Code. 10355488

Description

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. This lyohpilized protein should be reconstituted in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. This solution can be stored at 2°C to 8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein, such as 0.1% BSA and store in working aliquots at -20°C to -80°C. Storage: The lyophilized protein is stable at room temperature for 1 month, but should be kept at -20°C to -80°C for long term storage, preferably desiccated. Working aliquots stored with a carrier protein are stable for at least 12 months at -20°C to -80°C. Avoid repeated freeze/thaw cycles.

TGF beta-1 (TGFB1, Transforming Growth Factor Beta 1) is a polypeptide member of the transforming growth factor beta superfamily of cytokines, found almost ubiquitously in tissues. Transforming growth factor (TGF)-b is stored in the extracellular matrix as a latent complex with its pro-domain. Activation of TGF beta-1 requires the binding of aV integrin to an RGD sequence in the prodomain and exertion of force on this domain, which is held in the extracellular matrix by latent TGF-b binding proteins. Latent forms are complexes of TGF beta-1, an amino-terminal portion of the TGF-beta precursor, designated TGF-LAP (TGF-latency associated peptide), and a specific binding protein, known as LTBP. TGF beta-1 helps regulates proliferation, differentiation, adhesion, migration in many cell types. Many cells have TGF beta receptors, and the protein positively and negatively regulates many other growth factors. TGF beta-1 is cleaved into a latency-associated peptide and a mature TGF beta-1 peptide, and is found in either a latent form composed of a TGFB1 homodimer, a LAP homodimer, and a latent TGFB1-binding protein, or in an active form composed of a TGF beta-1 homodimer. The mature peptide may also form heterodimers with other TGF beta family members. The gene for TGF beta-1 is frequently upregulated in tumor cells, and mutations in this gene result in Camurati-Engelmann disease and cystic fibrosis.
