Figure 2: CLIP is produced by DR and DP5 but not DP4.

(a–c) Total cell lysates were immunoprecipitated and immunoblotted with indicated mAbs. Total cell lysates were prepared from T2 transfectants expressing the indicated class II as a single class II allele (a,b) and EBV-LCL homozygous for DP^84DEAV87 (DP5/17) or DP^84GGPM87 (DP4/4) (c).
