Mouse CD19 Protein (CD1-MM119) Summary
Product Description |
Recombinant Mouse CD19 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Arg19-Gly287. |
Product Background |
CD19 is a 95 kDa transmembrane glycoprotein that plays a central role in B cell activation and humoral immune responses. Functions as coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes. Decreases the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens. Activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca2 stores. |

Shipping, Reconstitution, & Storage
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
Stability And 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. |
