Product Description

B cells, also known as B lymphocytes, are a subtype of lymphocyte in white blood cells [1]. They play a critical role in the humoral immunity component of the adaptive immune system by secreting antibodies[1]. They also function in immune system as antigen presentation cells and by secretion of cytokines[1].

CD19 (Cluster of Differentiation 19) is an important surface marker for B cells from earliest recognizable B-lineage cells during development to B-cell blasts but is lost on maturation to plasma cells. CD19 primarily acts as a B cell co-receptor in conjunction with CD21 [2] 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.

iXCells Biotechnologies offers CD19+ B Cells isolated from normal human peripheral blood mononuclear cells (PBMCs) using negative immunomagnetic selection. > 90% of the cells are CD19+ as showed by flow cytometric analysis.
