Phos-tag™ Acrylamide

Phos-tag™ Acrylamide is an acrylamide-pendant Phos-tag™ molecule. Phos-tag™ SDS-PAGE, where a polyacrylamide gel containing Phos-tag™ is used, can be prepared by adding Phos-tag™ Acrylamide and MnCl2 in Resolving Gel when preparing SDS-PAGE gels. During migration, the phosphorylated proteins with the phosphate group bound to the divalent metal ions in Phos-tag™. This decreases the migration speed and phosphorylaed/non-phosphorylated proteins are separated. After separation, the gel can be utilized for western blotting and mass spectrometry. Various Phos-tag™ SDS-PAGE precast gels are also available. Please see 8.SuperSep Phos-tag™ on the page #19 for the details.

By simply adding Phos-tag™ Acrylamide and MnCl2 to an acrylamide solution when preparing SDS-PAGE gels Phosphorylated proteins are easily separable.

Development from Phos-tag™ SDS-PAGE

By a combination Phos-tag™ SDS-PAGE and various analysis methods, new information of phosphorylated proteins can be obtained.

Western blotting

Easily-recognizable phosphorylation of your target proteins Simultaneous detection of phosphorylated/non-phosphorylated proteins with a general antibody by their band shift differences. No need to prepare the phosphorylated antibody. Applicable to analysis of phosphorylation of endogenous proteins. Application Data
