Apexbio Technology LLC Sitagliptin (phosphate) 654671-78-0 250mg
Sitagliptin phosphate (CAS 654671-78-0) is a potent selective inhibitor of the enzyme dipeptidyl peptidase-4 (DPP4) DPP4 is a membrane-bound serine protease widely expressed on various cells involved in immune modulation signal transduction and apoptosis Sitagliptin competitively inhibits DPP4 activity exhibiting an IC50 value of approximately 18 nM with minimal cross-inhibition of structurally related proteases Clinically sitagliptin has shown efficacy in improving fasting and postprandial glycemic control and enhancing -cell function in type 2 diabetes research settings without increased cardiovascular risks
Cole-Parmer Stuart Flocculation Jar Tester, 6-place; 230 VAC, 50 Hz
These flocculators are designed for repeatable conditions between samples and from run to run. Speed control with electronic feedback accurately maintains the rotational speed of the stainless steel paddles. Two preset programs allow routine speed and time parameters to be entered, stored in memory, and recalled or altered at any time.
Portable tester 99551-00 holds two samples and features a handle for easy transportation. Tester 99551-05 has six positions and features a digital timer. Both testers accept 1-L beakers (not included).
