Application

New methylene blue N has been used as a photosensitizer for the photodynamic inactivation of Candida albicans.[1][2]

Biochem/physiol Actions

New methylene blue N can bind, neutralize and crosslink with RNA. This causes co-precipitation of ribosomal and residual RNA with the mitochondria and ferritin masses. These events make the living young erythrocytes as microscopically visible, dark-blue clusters and filaments, referred to as reticulum. New Methylene Blue N helps in counting of reticulocytes (erythrocytes containing RNA).[3]

Questions

  1. I would like to use this to stain blood smears to identify/count reticulocytes. What volume of stain would 1g of the powder make?

    1 answer

    1. Instructions for use are not available for this product. However, product R4132 is a prepared solution specifically for use in reticulocyte staining. The New Methylene Blue concentration of this solution is 1% or 1g/100 mL The product formulation is as follows:
      New Methylene blue, 1%
      Sodium Chloride, 0.9%
      Potassium Oxalate, 1.6%

      Based on the formulation listed above, the end-user will be able to prepare 100 ml of a 1% solution if using product 556416. This would also require the addition of the sodium chloride and potassium oxalate components.
      Please see the link below to review the product datasheet for the prepared stain R4132:
