Aptamer information 70.8 ± 5.6 nM
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 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.
