CD2 Protein, Human (HEK293, His)
Based on 1 Customer Validation
CD2 Protein, Human (HEK 293, His) is a transmembrane cell surface glycoprotein found on virtually all T cells, thymocytes, and NK cells. CD2 ligation by CD58 has been shown to mediate T cell adhesion, T cell activation, T cell cytokine production and T cell and NK cells cytotoxic activity.
- Species: Human
- Source: HEK293

Description
CD2 Protein, Human (HEK 293, His) is a transmembrane cell surface glycoprotein found on virtually all T cells, thymocytes, and NK cells. CD2 ligation by CD58 has been shown to mediate T cell adhesion, T cell activation, T cell cytokine production and T cell and NK cells cytotoxic activity.
Background
The human CD2 molecule is a transmembrane cell surface glycoprotein found on virtually all T cells, thymocytes, and NK cells. CD2 promotes the physical interaction of T-NK lineage cells with antigen-presenting cells (APCs), stromal elements, and a variety of target cells bearing the ubiquitously expressed CD2 ligand, CD58. In the case of T cells, CD2 fosters the initial stages of cell contact even prior to T cell receptor (TCR) recognition of a peptide antigen bound to a major histocompatibility complex (MHC) molecule (pMHC). Thus, unlike with integrin-based adhesion such as that mediated by CD11a/CD18 (LFA-1), CD2 adhesion function is independent of TCR triggering[1].
Verified Bioactivity
Loaded Siplizumab (HY-P99904) on AHC2 biosensor, can bind CD2 Protein, Human (HEK293, His) with an affinity constant of 3.775E-09 M as determined in BLI assay.

Product Properties
Lyophilized powder
Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
