Product No. CO-RO
Minimum volume to dissolve one tablet
It is possible dissolve 1 tablet in as little as 2 ml double distilled Water, results in a 25x stock solution, without difficulty. As this can take some time, leaving the solution at +15 to +25 °C for 30 - 60 min, or vortex.
cOmplete Inhibition of Endoproteinase Asp-N
cOmplete inhibits the metalloprotease endoproteinase Asp-N.
cOmplete tablets for use in preparing subcellular fractions from intestine
This has not been tested, but should work.
Using cOmplete tablets in cell culture
An application could be to express/produce a protein which is very protease sensitive.cOmplete Protease Inhibitor Cocktail can be used to inhibit proteases in the medium/supernatant of cell cultures. However, Roche has not systematically tested this application. cOmplete Tablets contain components which are membrane permeable, but not all are membrane permeable. In addition, the low molecular weight components which can enter cells have not been tested with regard to cytotoxicity. Several customers have reported using cOmplete tablets successfully in cell culture at a dilution of one-third to one-fourth of the working concentration indicated in the package insert. To determine the suitability of cOmplete tablets for your specific application empirically test different concentrations.
Effect of cOmplete Inhibitor on nucleases such as DNase I and RNase A
Roche has not systematically tested the effect of cOmplete Protease Inhibitor Cocktail Tablets on DNase I and RNase A.EDTA is a divalent chelator and can inactivate nucleases, such as Mg2+ required for DNase I activity. While low concentrations of EDTA are present in the reaction buffers of many restriction endonucleases, it may be best to use cOmplete EDTA-free Tablets.
Effect of cOmplete on phosphatases
cOmplete Protease Inhibitor Cocktail Tablets have not been systematically tested for inhibition of phosphatases by Roche.EDTA is known to inhibit alkaline phosphatase, so as indicated above, it may be best to use cOmplete EDTA-free Protease Inhibitor Tablets.
Removing cOmplete from preparations using dialysis
Use a dialysis membrane with a cut-off of >10 kDa.
