HumanHEK293Molecule · CD48 moleculeMolecular weight · 48.9 kDa

Product introduction

Recombinant Human CD48/SLAMF2 Protein is expressed in HEK293 cells with an hFc (IgG1) 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
Molecular weight: The protein has a predicted MW of 48.9 kDa. Due to glycosylation, the protein migrates to 62-72 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.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
Storage: -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: 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.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
