  • What type of polyacrylamide is used in oil industry?
  • The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
  • What is the difference between agarose and polyacrylamide?
  • In the case of DNA, polyacrylamide is used for separating fragments of less than about 500 bp. However, under appropriate conditions, fragments of DNA differing is length by a single base pair are easily resolved. In contrast to agarose, polyacrylamide gels are used extensively for separating and characterizing mixtures of proteins.
  • Can polyacrylamide Crosslinked hydrogels be used for 2-D gel electrophoresis?
  • Among the materials used for 2-D gel electrophoresis, polyacrylamide crosslinked hydrogels have been extensively investigated in the literature because their tunable mesh size porosity appears to be ideal for separating proteins and DNA samples ( Calvet et al., 2004, Manns, 2011 ).
  • Why are hydrogels based on acrylamide crosslinked with allyl agarose?
  • Such hydrogels are based on acrylamide crosslinked with allyl agarose. Mechanical and rheological tests are performed at varying crosslinker concentrations. Good separation of high molecular mass proteins is due to low crosslinking density. Non-permanent crosslinks allow an efficient resolution of smaller proteins. 1. Introduction
