Dear colleagues
I need the help for the antiurolithiatic activity, first I have three questions:
1- My problem is in choosing the standard, Cystone, it is not sold by Sigma Aldrich, Can I use the Cystone sold by the market (Amazon)?
2- My second question is about the second part of the activity (Aggregation assay): the Calcium oxalate is not soluble in the buffer solution, are that I can use directly in continuous agitation during the realization of the activity.
3- My last question that I can use sodium citrate as standard for antiurolithiatic activity
With my best regards
