CD22

A CD which is normally expressed in most B-cells (both immature and mature) but not typically expressed in plasma cells. Recall the CD_Mnemonic, "B" for "B-cells" & "Bigger" CDs (CD19, 20, 21, 22, 23, 24) which are typicaly expressed in "B-cells". Note: Unfortunately the function and expression profile of CDs larger than CD24 need to be memorized.
