Product Description
 Recombinant Human Latent TGF beta 1/TGFB1 Protein is expressed from HEK293 with His tag at the N-Terminus.It contains Leu30-Ser390 (C33S).
Product Background
 Latent TGF beta 1 -cDNA encodes a 390 amino acid precursor that contains a 29 aa signal peptide and a 361 aa proprotein. A furin‑like convertase processes the proprotein to generate an N‑terminal 249 aa latency‑associated peptide (LAP) and a C‑terminal 112 aa mature TGF‑ beta 1. Disulfide‑linked homodimers of LAP and TGF‑ beta 1 remain non‑covalently associated after secretion, forming the small latent TGF‑ beta 1 complex.

Amino Acid Range
 Leu30-Ser390(C33S)
Molecular Weight
 The protein has a predicted MW of 44.2 kDa. Due to glycosylation, the protein migrates to 40-50 kDa (LAP) / 13-15 kDa (Mature TGF Beta 1) based on Bis-Tris PAGE result.
Activity
 Immobilized Human Latent TGF beta 1, His Tag at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Human TGF-beta RII, hFc Tag with the EC50 of 86.1ng/ml determined by ELISA. See testing image for detail.
Product Tag
 N-His
Express System
 HEK293
Purity
 > 95% as determined by Bis-Tris PAGE
Endotoxin
 Less than 1EU per ug by the LAL method.
Form
 Lyophilized
Shipping
 Shipped at ambient temperature.
Formulation
 Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
 Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage
 Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
