Animal-Free TGF beta 3/TGFB3 Protein, Human (His)

Latent transforming growth factor beta-3 (TGF-beta-3) preprotein serves as a precursor to latency-associated peptide (LAP) and active TGF-beta-3 chains, which serve as regulatory and functional subunits. It plays a crucial role in maintaining the latent state of TGF-β-3 within the extracellular matrix. Animal-Free TGF beta 3/TGFB3 Protein, Human (His) is the recombinant human-derived animal-FreeTGF beta 3/TGFB3 protein, expressed by E. coli , with C-His labeled tag. This product is for cell culture use only.

Latent Transforming growth factor beta-3 (TGF-beta-3) proprotein serves as the precursor for both the Latency-associated peptide (LAP) and the active TGF-beta-3 chains, acting as the regulatory and functional subunits, respectively. It plays a vital role in maintaining the latent state of TGF-beta-3 within the extracellular matrix. Through non-covalent association with TGF-beta-3, Latent TGF-beta-3 actively regulates the activation process by interacting with key 'milieu molecules' such as LTBP1 and LRRC32/GARP. These interactions contribute to the controlled activation of TGF-beta-3, with LTBP1 and LRRC32/GARP acting as crucial components in this regulatory mechanism. Additionally, interaction with integrins induces structural changes in the Latency-associated peptide chain, leading to the subsequent release of active TGF-beta-3. This sophisticated molecular interplay underscores the pivotal role of Latent TGF-beta-3 in orchestrating the regulated activation of TGF-beta-3 in various physiological contexts.

Measure by its ability to inhibit IL-4-induce proliferation in HT-2 cells. The ED₅₀ for this effect is <50 pg/mL. The specific activity of recombinant human TGF beta 3 is > 2x10⁷ lU/mg.

Approximately 13 kDa, based on SDS-PAGE under reducing conditions.

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a solution containing 0.2 M NaCl, 20 mM sodium citrate, pH 3.5, trehalose or 20 mM sodium citrate and 0.2 M NaCl, pH 4.5.

<0.1 EU per 1 μg of the protein by the LAL method.

It is recommended to reconstitute to a concentration of 100-200 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
