Notes :Sample Prep Product: Strata-X-C, 30 mg/3 mL (Part No. 8B-S029-TBJ) Sample pre-treatment To 200uL Human urine sample add 100uL 0.1M ammonium acetate buffer (pH 4.0 ) in a glass test tube. Mix/vortex another 15 secs. Add 40uL b-Glucoronidase solution (100,000 units/mL from Campbell Science; Product # DR2102). Vortex 10-15 secs. Incubate for 2 hours in a shaker at 55o C to complete hydrolysis of the glucuronides. Add 400ul of 0.1% FA (formic acid) followed by vortexing for another 60 secs.
