BcMag™ One-Step Mouse Tail DNA Purification Kit

The process of extracting DNA from mouse tails or ears can be very time-consuming and requires a lot of labor. Specific applications, such as genotyping transgenic mice using a tail section, demand a lengthy DNA extraction method. Traditional methods involve a long process of digesting the tissue with proteinase K for several hours, followed by using chemicals like phenol and chloroform to extract the DNA and then precipitating it with alcohol. Recently, new techniques have emerged that use silica-based kits to purify DNA. These kits use high concentrations of a salt called guanidine hydrochloride to bind the DNA to silica. After binding, the DNA is washed with a solution of salt and ethanol to remove other substances from the sample, and then eluted with a buffer or water to obtain pure DNA. However, these methods can also be time-consuming and require multiple washing and spinning steps, which can result in DNA loss and shearing. Additionally, impurities can easily pass through the eluted DNA, affecting its purity and quantification, and potentially affecting downstream processes like PCR. BcMag™ One-Step Mouse Tail DNA Purification Kit allows rapid, column-free extraction of genomic DNA from mouse tail, ear, ear punch, or other animal tissue. The kit uses our unique proprietary magnetic beads and buffers to efficiently lyse cells and remove all impurities simultaneously in an aqueous buffer, leaving the DNA untouched. The procedure employs mild lysis conditions, avoiding harsh conditions such as alkaline lysis and toxic chemicals for lysing cells to maintain DNA integrity and the time-consuming cleanup of organic solvent from the sample. Furthermore, the magnetic beads eliminate PCR inhibitors from samples in a single step without DNA extraction. It increases DNA integrity, boosts nucleic acid yields, and minimizes DNA loss caused by typical DNA extraction techniques’ time-consuming “bind-wash-elute” procedure. Following sample lysis, the straightforward one-step extraction technique enables simultaneous processing of 96 samples and produces pure DNA in less than 30 minutes. Purified genomic DNA has the highest integrity and can be used in various downstream applications such as qPCR.
