说明

應用

Naphthol yellow S has been used as a staining agent in fixed human embryonic stem cell-derived cardiomyocytes.

生化／生理作用

Naphthol yellow S (NYS) is used as a stain for protein basic groups. It is an acidic dye and forms a NYS-protein complex at acidic pH. Combination of feulgen and NYS provides DNA to protein ratio.

分析報告

λ_max. ∼428 nm/∼392 nm; E(1%,1 cm) ∼275-425/∼250-400 (H₂O)
