DatasheetReviewsRelated ProductsProtocols
Rat CD5 Protein Product Information
Synonym:CD5
Protein Construction:A DNA sequence encoding the rat CD5 (P51882) (Met1-Pro368) was expressed, fused with a polyhistidine tag at the C-terminus.
Species:Rat
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Rat CD5 Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Bio-Activity:Immobilized rat CD5-His at 10 μg/ml (100 μl/well) can bind biotinylated human GST-LCK (Cat:10043-H09B), The EC50 of biotinylated human GST-LCK (Cat:10043-H09B) is 0.9-2.1 μg/ml.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Gln 24
Molecule Mass:The recombinant rat CD5 comprises 356 amino acids and predicts a molecular mass of 38.9 kDa. The apparent molecular mass of the recombinant protein is approximately 46-49 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Rat CD5 Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

    CD5 / Cluster of Differentiation 5 Background

    The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. CD5 is a member of the CD system. CD5 was found to be widely distributed in T-cells and B1 cells which is a subset of IgM-secreting B cells. CD5 also was found expressed in small lymphocytic lymphoma, hairy cell leukaemia and mantle cell lymphoma cells. CD5 serves to weaken the activating stimulus from the BCR so that the B1 cells can only reflect to the very strong stimuli but not the normal tissue proteins.
