High-molecular weight
Anything larger than 50 kb is considered HMW DNA, but there is a rapidly developing need for DNA that is much larger than that – several hundred kilobases, even into the megabase range. One of the traditionally used and inexpensive methods for obtaining HMW DNA into the megabase size range is phenol/ chloroform … See more DNA sequencing has traditionally involved reading short strands of DNA; it is cost-effective and accurate. Sanger sequencing, while not strictly short read sequencing because … See more NEB researchers have developed a novel approach that yields intact, HMW DNA by utilizing glass beads. It addresses a couple of the shortcomings of other technologies. Firstly, the beads are large – 4mm in diameter – … See more The need to extract intact, very HMW DNA quickly is essential so that researchers are not wasting precious time preparing the starting material for … See more WebIt can be calculated by adding the invididual molar mass of every atom that are composing the molecule (CH4 : 1 atom of C -> molar mass = 12.011 g/mol + 4 atom of H -> molar mass = 1.008 g/mol -> molar mass of CH4 = 12.011+4*1.008=16.043 g/mol)
