Descripciòn

Ponceau S (Acid Red 112) is a non-specific protein dye commonly used as a stain for Western blot. Ponceau S is used in an acidic aqueous solution that is compatible with antibody-antigen binding and dyes the proteins on the membrane red[1][2][3].

In Vitro

Concentration of Ponceau S (0.001-2 (w/v); 5-10 min), acid concentration and acid type (acetic acid, trichloroacetic acid/sulfosalicylic acid) doesn’t affect the sensitivity of protein detection[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

  • Calculadora de molaridad

  • Calculadora de dilución

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2
