產(chǎn)品屬性

TGF beta 1 Protein, Human, Rhesus, Cynomolgus, Canine, Recombinant: 產(chǎn)品信息
純度：> 95 % as determined by SDS-PAGE.
內(nèi)毒素：< 1.0 EU per μg of the protein as determined by the LAL method
生物活性：Measured by its ability to inhibit cell proliferation of Mv-1-lu mink lung epithelial cells.
The ED50 for this effect is typically 0.04-0.2 ng/mL.
蛋白構(gòu)建：A DNA sequence encoding the active form of human / rhesus / cynomolgus / canine TGFβ1 (NP_000651.3) (Ala 279-Ser 390) was expressed and purified. Human, Rhesus, cynomolgus and Canine TGFβ1 sequences are identical.
NP No.NP_000651.3
表達宿主：CHO Stable Cells
種屬：Human, Rhesus, Cynomolgus, Canine
預(yù)測 N 端：Ala 279
分子量：The recombinant human / rhesus / cynomolgus / canine TGFβ1 consists of 112 amino acids and has a calculated molecular mass of 12.8 kDa. it migrates as an approximately 13 & 26 kDa band in reduced and non-reduced SDS-PAGE respectively, corresponding to the monomer and homodimer.
緩沖液：Lyophilized from sterile 100mM GLY, 10mM NaCl, pH 3.0
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
運輸方式：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.
穩(wěn)定性 & 儲存條件：Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

復(fù)溶：A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
