Ethidium Bromide
IBI ScientificEthidium Bromide can be used to detect both single and double stranded nucleic acids (both DNA and RNA). However, Ethidium Bromide does not intercollate into single-stranded DNA very well; therefore, the fluorescence of single-stranded DNA is relatively poor in comparison to double-stranded DNA.…

6X Loading Dye
IBI ScientificIBI’s ready-to-use 6X loading dye is ideally suited for agarose electrophoresis of DNA, RNA, or nucleic acids. Its ultra pure grade ensures quality and repeatibility every time you use it. The light blue, indigo, and magenta dyes will clearly show the migration of each run, and the dyes…

IPTG
IBI ScientificIPTG is an inducer of β-galactosidase activity in E. coli. It is commonly used in conjunction with X-GAL to detect lac gene expression in cloning applications, thus allowing detection of recombinant molecules.

X-Gal
IBI ScientificX-GAL is histochemical substrate for β-galactosidase, allowing the detection of lac gene expression. To make a stock solution of X-GAL, dissolve the X-GAL in dimethylformamide to make a 20mg/ml solution. Note: Use either a glass or polypropylene tube. Add 4ml of this solution per liter of…
