Description
CD2-like receptor activating cytotoxic cells (CRACC), also known as CS1, SLAMF7, and CD319, is a 65-75 kDa type I transmembrane glycoprotein in the SLAM subgroup of the CD2 family. Within the ECD, human CRACC shares 54% and 52% aa sequence identity with mouse and rat CRACC, respectively. There are seven known isoforms of CRACC which are distinguished by deletions and/or substitutions in both their ECD and cytoplasmic domains. CRACC is expressed on the surface of NK cells, CD8+ T cells, activated B cells, and mature dendritic cells.

Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
|
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL` is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
Storage
The product should be stored at -20~-80℃ for 1 year from date of receipt.
2-7 days, 2 ~8 °C under sterile conditions after reconstitution.
3-6 months, -20~-80℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
