Recombinant Human CD83 protein, His-tagged

Specification :
| Description : CD83 antigen is also known as B-cell activation protein and Cell surface protein HB15. CD83 is a single-pass type I membrane protein which contains one Ig-like V-type (immunoglobulin-like) domain. CD83 is expressed by activated lymphocytes, Langerhans cells and interdigitating reticulum cells. CD83 may play a significant role in antigen presentation or the cellular interactions that follow lymphocyte activation. | Source : HEK293 | Species : Human | Tag : His | Predicted N Terminal : Thr20 | Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose. | Molecular Mass : The protein has a calculated MW of 14.9 kDa. The protein migrates as 18 kDa and 22 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation. | Protein length : Thr20-Ala143 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | Purity : >95% as determined by SDS-PAGE. | Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.Please avoid repeated freeze-thaw cycles.This product is stable after storage at:-20 to -70 centigrade for 12 months in lyophilized state;-70 centigrade 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℃ before opening to recover the entire contents.
