Accurate-Glycine-SDS-PAGE™, 4-12% Gel Strength, Cross Linking 29:1 (10 GELS) € 110.00 Add to cart.Tricine-SDS-PAGE, 4-16% Gel Strength, Cross Linking 29:1 (10 Gels) € 110.00 Add to cart.If you feel certain that your protein is not crosslinking so much that it can not enter the gel than I would think about the pH of the sample and the effect of Cu ions on the stacking effect of the stacingk gel. Accurate-Tricine-SDS-PAGE™ 4-16% Gel Strength, Cross Linking 29:1 (10 Gels) € 110.00 Add to cart At the interface of the stack gel and resolving gel is a pH change and a change in gel density.Owl Scientific: Penguin P8DS, Wolverine P82 (needs adapter), P81 Puffin (single sided) and Fisher Biotech: FB-VE10-1, FB-VE121. The stacking was 6.8 and the separating gel was 8.8. CBS Scientific: MGV-402, MGV-302 (one gel). I just made a SDS-PAGE with a top layer of stacking gel and a bottom layer of separating gel with different pH values of 0.5M Tris-HCl. Invitrogen-Novex: Surelock, XCell I and II. Bio-Rad: Protean II, III (Protean III fits one gel), Tetra (and Tetra Transblot), Mini Protean 3 Dodeca. The gel cassettes fit with commercially available vertical gel electrophoresis system such as: Hoefer-GE: Mighty Smalls SE250, SE260, MiniVE SE300. They are cost effective and highly reproducible with shelf life of 3-4 months at 4✬. These gradient gels are prepared under the supervision of the qualified scientists. So, each gradient gel has a zone or layer of specific gel strength. Here we designed a new gradient gel systems which are specially prepared by hand casting. Gradient gels are generally cast by employing some conventional methods. These gels are specially very useful when sample contains proteins with unknown molecular weight or enough information is not available about the protein of interest. Gradient SDS-PAGE gels are commonly used for the separation of peptides and proteins.
