Human CD99, His Tag (CD9-H5221) is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 122 (Accession # AAH02584).
Predicted N-terminus: His
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 10.9 kDa. The protein migrates as 25 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

CD99 antigen is also known as MIC2, single-chain type-1 glycoprotein, HBA71, MIC2X, MIC2Y, MSK5X, 12E7, which belongs to the CD99 family. CD99 / MIC2 is expressed on all leukocytes but highest on thymocytes. Involved in T-cell adhesion processes and in spontaneous rosette formation with erythrocytes. CD99 / MIC2 plays a role in a late step of leukocyte extravasation helping leukocytes to overcome the endothelial basement membrane. CD99 acts at the same site as, but independently of PECAM1. There is also experimental evidence that it binds to cyclophilin A.
