>I would like to concentrate nucleosides in urine with molecular weights
up to 240 and I am thinking of using cut-off filters. However, cut-off
filters specify only kDa. Does anyone know of a formula to convert
molecular weight to kDa/
I'll resist the urge to be a smartass and just answer the
question. 1 kDa = 1000 Da = MW 1000. So MW 240 = 0.24 kDa. You would
probably have better luck using a chromatographic method.
