ALK-1 Protein, Rat, Recombinant (His & hFc Tag): 产品信息
纯度
> 90 % as determined by SDS-PAGE
内毒素
< 1.0 EU per μg of the protein as determined by the LAL method
生物活性
Measured by its ability to inhibit BMP9-induced alkaline phosphatase production by MC3T3E1 mouse chondrogenic cells. David, L. et al. (2007) Blood 109:1953.
The ED50 for this effect is typically 40-200 ng/mL in the presence of 2 ng/mL of recombiant human BMP9.
蛋白构建
A synthetic DNA sequence encoding the rat ACVRL1 (NP_071886.1) extracellular domain (Met 1-Ala 118) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
分子量
The secreted recombinant rat ACVRL1/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer comprises 343 amino acids with a predicted molecular mass of 38.7 kDa. As a result of glycosylation, it migrates as an approximately 50-55 kDa band in SDS-PAGE under reducing conditions.
缓冲液
Lyophilized from sterile PBS, pH 7.4
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.
运输方式
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.
稳定性 & 储存条件
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.
复溶
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
