ATW0019 Aptamer to Human Protein Target, CD19

B lymphocyte antigen CD19 also known as CD19 (Cluster of Differentiation 19), is a protein that in humans is found on the surface of B cells, a type of white blood cell. It primarily acts as a B cell co-receptor in conjunction with CD21 and CD81. Upon activation, the cytoplasmic tail of CD19 becomes phosphorylated, which leads to binding by Src-family kinases and recruitment of PI-3 kinase.

Target:   CD19

Target Species:   human

Target Type:   protein

Affinity Constant (Kd):   70.8 nM

Default 3' Linker (Spacer) is 10T. Please submit a custom quote request for other options.

This aptamer was selected by scientists at Base Pair Biotechnologies using proprietary methods and Recombinant CD19 Human Proteins, Sino Biological Inc., [Cat# 11880-H08H] as a target and 1X PBS, pH = 7.4.  Let us know if you have any questions about its development or potential uses.

Base Pair Bio

Antibody Equivalent Units (AEU).  There is a  large molecular weight difference in antibodies (typically 150,000 Da) and Base Pair’s aptamers (~14,000 Da).   We provide our aptamers in terms of moles, where the aptamer moles in 1  AEU is equal to antibody moles in the typical 100 microgram shipment from a leading antibody vendor. Therefore our standard 2.5 AEU (25ug) or 5 AEU (50ug) delivery is 2.5 and 5 times the equivalent moles of a standard antibody delivery of 100 microgram respectively.
