The absolute quantitation module contains both AQUA Ultimate HeavyPeptides Mixture and AQUA Ultimate LightPeptides Mixture. For the absolute quantitation module, the standard curve is generated by serially diluting the light peptides against a constant backdrop of heavy peptides in order to obtain a ratio. The matrix for dilution is the Pierce 6 Protein Digest Standard Equimolar, LC/MS Grade that also serves as a constant. The relative quantitation module contains only AQUA Ultimate HeavyPeptides Mixture as a positive control.

We've tested only human cells and tissues, although these kits can theoretically be used with any mammalian cells or tissues. We've tested fresh and fresh-frozen samples, both normal and tumor cells and tissues.

SureQuant kits enable multiplex immunoprecipitation to mass spectrometry (mIP-MS) for the simultaneous enrichment and quantitation (absolute or relative) of multiple total and phosphorylated proteins (13 in total, including 11 phosphorylated states) in the AKT/mTOR signaling pathway.
For each pathway, we offer i) a pathway-specific IP-MS sample preparation module which includes all the reagents necessary to immunoenrich AKT/mTOR pathway proteins and perform in-solution MS sample preparation from sample lysis through peptide clean-up and ii) a quantitation module (relative or absolute), which includes a system suitability standard to monitor MS performance and AQUA Ultimate Heavy and /or Light Peptide mixtures for peptide quantitation. For each pathway, we also offer iii) a multiplex panel which is a combo kit comprising both IP-MS sample preparation and quantitation modules. Two versions of each multiplex panel are offered with either a relative or absolute quantitation module.
