Product Details

Molecular Aliases
CD7 molecule; CD7; LEU-9; Tp40; TP41; GP40; LEU9
Protein Length
Ala26-Pro180
Expression System
HEK293
Theoretical Molecular Weight
The protein has a predicted MW of 19.3 kDa. Due to glycosylation, the protein migrates to 34-48 kDa based on Bis-Tris PAGE result.
Purity
> 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin
Less than 1 EU per μg by the LAL method.
Buffer / Formulation
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State
Lyophilized
Storage Conditions
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution Advice
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background

CD7, also known as Leu-9, is an approximately 40 kDa glycosylated and palmitoylated transmembrane protein in the immunoglobulin superfamily. CD7 is expressed on T cells, NK cells, myeloid progenitor cells, and CD19 B progenitor cells. Among CD8 T cells, the CD7-bright population preferentially contains naïve and memory cells, while more weak expressors are primarily effector cells.
