(a) Plot comparing the log2 transcript abundance of CD22, CD72, and CD19 by microarray analysis of a DLBCL patient cohort (GSE12195, n=73). (b) CD72 transcript abundance by microarray analysis of ABC and GCB subtypes of DLBCL patient samples (GSE11318, n=203 and GSE23967, n=69). (c) Quantification of CD72 abundance by immunohistochemistry (IHC) staining of banked DLBCL patient samples (total, n=28) displayed by ABC or GCB subtype. (d) Representative raw images of CD72 staining intensity by IHC of two different DLBCL patient samples.
