Active Recombinant Human CTGF protein, His-Avi-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His-Avi | Form : Lyophilized from 0.22 μm filtered solution in Tris with Potassium glutamate and Arginine, pH7.0. Normally trehalose is added as protectant before lyophilization. | Bio-activity : Immobilized Biotinylated Human CTGF Protein, His,Avitag at 2 μg/mL (100 μL/well) on streptavidin precoated (0.2 μg/well) plate, can bind Monoclonal Anti-Human CTGF Antibody, Human IgG1 with a linear range of 0.6-5 ng/mL. | Molecular Mass : This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).The protein has a calculated MW of 39.2 kDa. The protein migrates as 40-42 kDa and 43-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. | Protein Length : Gln 27 – Ala 349 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | Purity : >90% as determined by SDS-PAGE. | Storage : For long term storage, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
