  • WB analysis of Ramos using 66103-1-Ig (same clone as 66103-1-PBS)

    WB analysis of Ramos using 66103-1-Ig (same clone as 66103-1-PBS)

    Ramos, Daudi, and Raji cells were subjected to SDS PAGE followed by western blot with 66103-1-Ig (CD22 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66103-1-PBS in a different storage buffer formulation.

  • WB analysis of Raji using 66103-1-Ig (same clone as 66103-1-PBS)

    WB analysis of Raji using 66103-1-Ig (same clone as 66103-1-PBS)

    Untreated and PNGase F-treated lysates of Raji cells were subjected to SDS PAGE followed by western blot with 66103-1-Ig (CD22 antibody) at dilution of 1:20000 incubated at room temperature for 1.5 hours. PNGase F was obtained from Atagenix (cat.NO. ata808). This data was developed using the same antibody clone with 66103-1-PBS in a different storage buffer formulation.

背景介绍

CD22, also known as Siglec-2 (sialic acid binding Ig-like lectin 2) or BL-CAM (B-lymphocyte cell adhesion molecule), is a 130-140 kDa, B-cell restricted, type I transmembrane glycoprotein belonging to the immunoglobulin gene superfamily. The expression of CD22 is developmentally regulated. It is expressed at low levels in the cytoplasm of pro-B and pre-B cells and present on the cell surface only at mature stages of B-cell differentiation. Cell surface expression is lost during terminal differentiation into plasma cell and after B-cell activation. CD22 is an inhibitory receptor for B-cell receptor (BCR) signalling, preferentially binds to alpha-2,6-linked sialic acid and mediates B-cell B-cell interactions. It plays a crucial role in activation and differentiation of the B-cell.
