Biological Activity

Pyronin Y (Pyronine G) is a cationic dye that intercalates RNA and has been used to target cell structures including RNA, DNA and organelles. Pyronin Y forms fluorescent complexes with double-stranded nucleic acids (especially RNA) enabling semi-quantitative analysis of cellular RNA. Pyronin Y can be used to identify specific RNA subspecies of ribonuclear proteins complexes in live cells.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
