Hello, I am working with the aforementioned reagent, but my problem arises that the reagent does not indicate the quantity of particles that come per vial, that is, the number of particles, it only gives me the concentration, which is 1 mg/ml in 2 ml. . My question is if anyone has worked with this reagent and can tell me the number of particles.

Thank you so much

im really sorry for my grammar, english is not my first language.
