Human Latent TGF-beta 1 / TGFB

分子别名（Synonym）:CED,DPD1,LAP,TGF-beta 1,TGFB,TGFbeta 种属（Species）：Human 表达系统（Expressed Host）：HEK293 Cells 制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4 分子量（Molecule Mass）：The recombinant human latent TGFβ1 consists of 370 amino acids and has a calculated molecular mass of 42.4 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh TGFβ1 is approximately 16, 38 and 55 kDa corresponding to mature TGFβ1, LAP protein and inacitve latent TGFβ1 respectively due to glycosylation. In non-reduced SDS-PAGE, it migrates as an approximately 110 kDa protein consisting of a TGFβ1 homodimer non-covalently linked to a LAP homodimer. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Measured by its ability to bind biotinylated Human ALK1-Fc (Cat:H1290-202H) in functional Elisa. 表达区间（Protein Construction）：A DNA sequence encoding the full length of human TGFβ1 (NP_000651.3) (Ser 2-Ser 390) was fused with a C-terminal polyhistidine tag. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
