i am working in lateral flow assay and for that, i want to measure antibody in milligram and unfortunately, milligram weight balance is not available
so i am not sure if i can weigh in gram and can get the same concentration
so can i got the same concentration if we use gram and dissolve in buffer solution
i want 1 mg/ml solution
