Product overview
Recombinant Biotinylated Human CD48/SLAMF2 Protein is expressed in HEK293 cells with a His tag and Avi tag at the C-terminus. It contains amino acid residues Gln27-Ser220 (UniProt accession: P09326-1).
Product Details
- Molecular Aliases
- CD48 molecule; CD48; SLAMF2; BCM1; BLAST; BLAST1; BLAST1TCT.1;- mCD48; MEM-102; TCT.1; MEM102
- Protein Length
- Gln27-Ser220
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 25.25 kDa. Due to glycosylation, the protein migrates to 45-60 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
CD48, also known as BLAST-1, BCM-1, and SLAMF2, is a 65 kDa GPI-linked protein in the CD2 family of immunoglobulin superfamily molecules. CD2 and 2B4 (CD244) are known ligands for CD48. CD48 protein is expressed on most lineage-committed hematopoietic cells but not on hematopoietic stem cells or multipotent hematopoietic progenitors.
