Description: S-adenosylmethionine (SAM) is a substrate for methyl transfers to various biomolecules that yields S-adenosylhomocysteine (SAH). SAH is then hydrolyzed to homocysteine and adenosine, which is converted to methionine, and ultimately back to SAM. SAH can act as a methylation inhibitor, therefore the SAM/SAH ratio, or methylation potential, is important for maintaining proper methylation in the cell. Our S-Adenosylmethionine (SAM) and S-Adenosylhomocysteine (SAH) ELISA Combo Kit is designed for detection and quantitation of both SAM and SAH in plasma, serum, lysates, or biological fluid samples. This assay is a competitive ELISA where samples and an anti-SAM or anti-SAH antibody are added to a plate coated with a SAM or SAH conjugate. The sample and conjugate compete for antibody binding, which generates a reverse curve. Samples with high SAM and SAH levels will bind the majority of the antibody, which gets washed away and results in a low OD, while samples with low SAM and SAH levels will leave more antibody available to bind to the conjugate, producing a high signal.

Description: CytoSelect 96-Well Cell Transformation Assays (Cell Recovery Compatible) provide a robust system for detecting transformed cells, screening cell transformation inhibitors, and determining in vitro drug sensitivity. A proprietary modified soft agar matrix allows you to either quantify cells using the included fluorescent dye, or recover the cells for further analysis.

Description: Our StemTAG 96-Well Stem Cell Colony Formation Assay provides a high-throughput method to quantify ES cells in just 7-10 days, and no manual cell counting is required. Once colonies are formed, they may be analyzed in three different ways: 1. Lyse cells, then quantify in a fluorescence plate reader using dye included in the kit; 2. Lyse cells, then quantify alkaline phosphatase activity using reagents provided; or 3. Recover colonies from matrix for further culture or analysis.
