Figure 1. RNA Polymerase II is present in mouse sperm nuclei.

Figure 1

Protein extracts prepared from mouse sperm nuclei or a mouse C2C12 cell line (as a control) were separated on a 8% SDS polyacrylamide gel and assayed by western blot using mouse monoclonal antibodies against the largest subunit (Rpb1) of RNA Polymerase II (Covance). Prestained protein markers were used to indicate molecular weight (kDa). Images shown are from the same gel but separated by 2 empty lanes to eliminate cross contamination. Images are representative of results obtained from extracts prepared from two different groups of mice (two mice per group).
