CD19 Antibodies
CD19 (Cluster of Differentiation 19) is a type I transmembrane glycoprotein belonging to immunoglobulin (Ig) subfamily that is a biomarker for B cells and plays a role in B cell signaling and immune response. The human CD19 protein is 556 amino acids (aa) in length with a theoretical molecular weight of 61 kDa. We offer CD19 antibodies in our catalog have been cited in over 25+ publications, including 5-star customer reviewed antibodies.
