Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2 It is a white odorless solid soluble in water and several organic solvents It is produced industrially as a precursor to polyacrylamides which find many uses as water-soluble thickeners and flocculation agents It is highly toxic likely to be carcinogenic and partly for that reason it is mainly

Polyacrylamid (PAM) ist ein Polymer von Acrylamid Polyacrylamid lsst sich aus Acrylamid in wssriger Lsung durch radikalische Polymerisation herstellen Die Reaktion kann z B von Ammoniumpersulfat (APS) als Radikalstarter eingeleitet und von Tetramethylethylendiamin (TEMED) katalysiert werden Polyacrylamid ist wasserlslich oder zumindest wird es von Wasser angequollen

Polyacrylamide gel electrophoretic studies of the water-insoluble phases of the large nerve vesicles and the chromaffin granules have revealed some similarities (Helle Lagercrantz 1972 Bartlett Lagercrantz Smith 1976) 16–20 protein bands were reproducibly found in extracts of the large nerve vesicle preparation and six of these were found to correspond to protein bands in

Serology testing that accurately detects antibodies to the SARS-CoV-2 coronavirus is a foundational tool needed to select appropriate measures to control the COVID-19 pandemic and assess the performance of candidate human vaccines Premkumar et al used the receptor-binding domain (RBD) portion of the SARS-CoV-2 spike protein to develop an immunoassay that detects RBD-binding antibodies in

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene) abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits It can be synthesized as a simple linear-chain structure or cross-linked typically using N N '-methylenebisacrylamide In the cross-linked form the possibility of the monomer being present is reduced even further

The present invention provides polyacrylamide hydrogels (especially polyacrylamide hydrogel arrays) made from prepolymers and polyacrylamide reactive polymers as well as methods and compositions for preparing the polyacrylamide hydrogels or hydrogel arrays The method advantageously provides greater control of polyacrylamide pore size and crosslink density allowing for instance preparation
