This assay has high sensitivity and excellent specificity for detecting Human CD59 (Cluster of Differentiation 59). The assay range is from 12.5 to 800 pg/ml (Sandwich kit) with a sensitivity of 5.4 pg/ml. There is no detectable cross-reactivity with other relevant proteins. Activity loss rate and accelerated stability test ect have been conducted to guarantee the best performance of the products after long storage and delivery.

• High sensitivity and specificity
• Perfect reproducibility and consistency across batches
• Quality control with three-level inspections
• Wide range of targets/species available
• Intra-assay: CV<10%; Inter-assay: CV<12%

Protectin, a cell surface glycoprotein that regulates complement-mediated cell lysis, and it is involved in lymphocyte signal transduction. This protein is a potent inhibitor of the complement membrane attack complex, whereby it binds complement C8 and/or C9 during the assembly of this complex, thereby inhibiting the incorporation of multiple copies of C9 into the complex, which is necessary for osmolytic pore formation. This protein also plays a role in signal transduction pathways in the activation of T cells. Mutations in this gene cause CD59 deficiency, a disease resulting in hemolytic anemia and thrombosis, and which causes cerebral infarction. Multiple alternatively spliced transcript variants, which encode the same protein, have been identified for this gene.
