Abstract:

An improved Stains-All (ISA) staining method for phosphoproteins in SDS-PAGE was described. Down to 0.5-1 ng phosphoproteins (α-casein, β-casein, or phosvitin) can be successfully selectively detected by ISA stain, which is approximately 120-fold higher than that of original Stains-All stain, but is similar to that of commonly used Pro-Q Diamond stain. Furthermore, unlike the original Stains-All protocol that was time consuming and light unstable, ISA stain could be completed within 60 min without resorting to protect the gels from light during the whole staining procedure. According to the results, it is concluded that ISA stain is a rapid, sensitive, specific, and economic staining method for a broad application to the research of phosphoproteins.
