Human recombinant TGF beta 1 (Transforming growth factor beta 1) protein, AF

Q: What is the catalog number for Human recombinant TGF beta 1 (Transforming growth factor beta 1) protein, AF?

The catalog number for Human recombinant TGF beta 1 (Transforming growth factor beta 1) protein, AF is PROTP01137-10-100ug.

The transforming Growth Factors beta (TGF beta) family of cytokines are ubiquitous, multifunctional, and essential to survival. They play the central roles in growth, development, inflammation, repair, and host immunity. The mammalian TGF beta isoforms (TGF beta 1, beta 2 and beta 3) are secreted as potential precursors and possess a variety of cell surface receptors and produces at least two mediate signal transductions.

Applications

Cell Culture

Purification

>95% as determined by SDS-PAGE.

Endotoxin

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

Bioactivity

Measure by its ability to inhibit the IL-4 dependent proliferation in TF-1 cells. The ED50 for this effect is < 0.1 ng/mL.

Form

The protein was lyophilized from a 0.2 μm filtered solution of PBS, pH 7.0. If you have any concerns or special requirements, please confirm with us.

Reconstitution

Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile 10 mM HCl to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.

Molecular Weight

The protein has a calculated MW of 44.3 kDa. The protein migrates as approximately 10、40、50 kDa under reducing condition (SDS-PAGE analysis) corresponding to mature TGFβ1, LAP protein and inacitve latent TGFβ1 respectively due to glycosylation

Storage Conditions

Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
