蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 14.9 kDa. The protein migrates as 17-18 kDa, 20-22 kDa and 25-30 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳（SDS-PAGE）
Human CD83, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
背景（Background）
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.
