SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 KDa The combined use of sodium dodecyl sulfate (SDS also known as sodium lauryl sulfate) and polyacrylamide gel allows to eliminate the influence of

Plant Responses to High Frequency Electromagnetic Fields

High frequency nonionizing electromagnetic fields (HF-EMF) that are increasingly present in the environment constitute a genuine environmental stimulus able to evoke specific responses in plants that share many similarities with those observed after a stressful treatment Plants constitute an outstanding model to study such interactions since their architecture (high surface area to volume

Discontinuous electrophoresis

Discontinuous electrophoresis (colloquially disc electrophoresis) is a type of polyacrylamide gel electrophoresis It was developed by Ornstein and Davis This method produces high resolution and good band definition It is widely used technique for separating proteins according to size and charge Method In this method the gel is divided into two parts resolving and stacking gel both have

RecBCD Enzyme and the Repair of Double

SUMMARY The RecBCD enzyme of Escherichia coli is a helicase-nuclease that initiates the repair of double-stranded DNA breaks by homologous recombination It also degrades linear double-stranded DNA protecting the bacteria from phages and extraneous chromosomal DNA The RecBCD enzyme is however regulated by a cis -acting DNA sequence known as Chi (crossover hotspot instigator) that

How SDS

How SDS-PAGE Works Published July 13 2016 SDS-PAGE (sodium dodecyl sulphate-polyacrylamide gel electrophoresis) is commonly used in the lab for the separation of proteins based on their molecular weight It's one of those techniques that is commonly used but not frequently fully understood So let's try and fix that SDS-PAGE separates proteins according to their molecular weight
