HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY SYT4 (RC206304, Right lane) cDNA for 48 hrs and lysed. Equivalent amounts of cell lysates (5 ug per lane) were separated by SDS-PAGE and immunoblotted with anti-SYT4. Positive lysates LY412338 (100 ug) and LC412338 (20 ug) can be purchased separately from OriGene.
