Sds page gel recipe molecular cloning. 9 methods for sds page to prepare the crude extract samples for gel electrophoresis first obtain the 250 µl cell pellets that were stored at 20 c. Pour gel leaving 2 cm below the bottom of the comb for the stacking gel. Sds polyacrylamide gel electrophoresis of proteins joseph sambrook and david w. In order to target proteins with mws between 20 and 200 kda you will need to create a conventional sds page gel using the recipes shown below.

After adding temed and aps to the sds page separation gel solution the gel will polymerize quickly so add these two reagents when ready to pour. Calculate polyacrylamide gel recipes for sds page just enter the number of gels 18x16mm and the percent polyacrylamide needed enter the number of gels. Resuspend the pellets in 50 µl of distilled h2o pipet up and down and vortex to get the entire cell pellet resuspended. By using markers of known molecular weight the molecular weight of the polypeptide chain s can be estimated.
