  • IPTG

    IBI Scientific

    IPTG 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.

  • Rapid : 15 minute, non-toxic, safe, 1-step stain. No organic solvents! No phosphoric acid! Sensitive : 50 times more sensitive  than other rapid stains. Lower limit is 5 ng protein standard. Linear Range : Very low background enabling accurate quantitation of proteins. High…

  • X-Gal

    IBI Scientific

    X-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…

  • 6X Loading Dye

    IBI Scientific

    IBI’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…

  • Seeband Protein Stain is a convenient alternative to traditional coomassie blue staining procedures. Environmentally friendly, this ready-to-use stain does not contain methanol or acetic acid, and does not require hazardous solvents for destaining. This simple “hands-off ” staining/destaining…

  • Ethidium Bromide

    IBI Scientific

    Ethidium 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.…
