Background: Siglec-2/CD22

CD22 is a single-pass type 1 membrane glycoprotein found in the cytoplasm and cell membrane of B-lymphocytes. CD22 has at least two isoforms (alpha and beta) produced by alternate splicing. The protein exists predominantly as a monomer of the beta isoform (95 kDa). It is also found as a heterodimer of the beta and alpha isoforms.

    • Q: I am interested in buying a CD22 antibody for fluorescence microscopy and FACS I red on your web page that you also offer to label your antibodies, if required, is that correct?
      A: We do have the ability to perform custom conjugations on certain antibodies, including some to the CD22 protein. If you send me the conjugate you are interested in I can provide you with a quote.
