Handhabung

Format: Lyophilized

Rekonstitution: Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1 mg/mL for 500 μg or 1 mg lyophilized powder. Do not mix by vortex or vigorous shaking.

Buffer: Lyophilized from 0.22 μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.

Lagerung: -20 °C,-80 °C

Informationen zur Lagerung: -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.

Haltbarkeit: 12 months

Antigendetails

Target: CD19 (CD19 Molecule (CD19))

Andere Bezeichnung: CD19

Hintergrund: 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.

Molekulargewicht: 30.96 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result.
