Arthus Biosystems is pleased to provide a series of research reagents and kits to help perform scientific research related to methionine cycle, the critical biochemical pathway that is conserved throughout evolution. Both our anti-SAM and SAH antibodies have the best sensitivities, and are meant to specifically bind all forms of SAM and SAH in a variety of studies and species. We also provide verified SAM and SAH conjugates with tracer molecules such as biotin and digoxin to assist you in developing further research methods. We also provided HRP and fluorescent materials conjugated monoclonal antibodies against SAM and SAH for use conveniently and specifically in a variety of immunoassays for the purposes of quantification and intra-cellular or nuclear localization. The immunofluorescence chromatography test strips provide users with yet other ways to quantify SAM and SAH conveniently and quickly. This method has a few advantages including a better sensitivity, broader detection ranges, quick (in 15 minutes) and broader sample types (serum, plasma and whole blood drop).
