the information sheet says that it is soluble to 0.1mg/ml. are you trying to make it too concentrated?

it may take a little time to fully solubilize.

Solubility is usually a matter of pH, salt and something else (glycerol, BME, EDTA etc.).
Got to play around with these factors and identify the sweet spot (or look it up in a publication that goes into a description of the buffer).
