  • Increasing implementation of waste water

    Global polyacrylamide market is anticipated to witness a significant growth over the upcoming years on account of the rising awareness of the waste water management. Polyacrylamide is a water soluble polymer. Thus, these water soluble polymers are used for separation of proteins and water treatment. Polyacrylamides are produced in liquid form or granular form and are available as anionic, non ...

    2011-6-17 · The basics. Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1−1000 base pairs, based on the concentration used (Figure 1). These gels can be run with or without a denaturant. Gels that are run without a denaturant are referred to as native gels.

    FAQ: Why are there extra bands visible on polyacrylamide gels? To provide increased intensity for the smaller bands and the reference bands, multiple fragments of the same size have been cloned into the plasmids used for many of the DNA ladders. These fragments, identical in size, are indistinguishable on agarose gels, but, on acrylamide gels ...
