This product is a single phosphorylated protein that can be used as a positive control of phosphorylation for on-membrane detection (Western Blot). The product has already been denatured in LDS and DTT and can be immediately loaded onto a gel (load 10uL per well). Can be used to confirm that pIMAGO-based detection is working properly or for other phosphorylation detection applications. The product contains 100uL of the denatured protein (enough for 10 blots).
