MYD88 L265P in DLBCL and WM cell lines and primary WM patient cells using conventional AS-PCR assay. Detection of MYD88 L265P in OCI-LY3 and OCI-LY19 DLBCL, BCWM.1, and MWCL-1 WM cell lines (A) and primary WM patient tumor cells isolated from BM aspirates (B) by conventional AS-PCR assay. The depicted zygosity of MYD88 L265P in primary WM patient cells shown was confirmed by WGS. The position of MYD88 L265P locus is indicated by arrows. Complementary strand sequences are shown.
