Bacstain- Bacterial Viability Detection Kit-dapi/PI uses bacterial membrane damage as an index. DAPI is a minor grove binder specific to the AT sequence of DNA nd permeates into bacteria to stain nucleic acids regardless of membrane damage. PI is a parallel intracalator into the DNA double helix that stains nucleic acid; it passes only through damaged bacterial membranes. Thus, this Kit can be used to measure the ratio of membrane-damaged bacteria to total bacteria on analysis of the fluorescence images fro each stain.

Bacstain- Bacterial Viability Detection Kit – CFDA/PI uses esterase activity of bacteria and bacterial membrane damage as an index. CFDA is hydrolyzed to carboxyfluorescein?which is fluorescent?by intracellular esterase. PI is a parallel intercalator into the DNA double helix that stains nucleic acids; it passes only through damaged bacterial membranes. Thus, this kit can be used to measure the ratio of bacteria with esterase activity to membrane-damaged bacteria on the analysis of the fluorescent images from each stain.

Bacstain- Bacterial Viability Detection Kit – CTC/DAPI uses respiratory activity of bacteria as an index. CTC produces formazan dye upon reduction by NAD(P)H formed by bacterial respiratory activity, and hence selectively stains active bacteria. DAPI is a minor groove binder specific to the AT sequence of DNA and permeates into bacteria to stain nucleic acids regardless of membrane damage. Thus, this kit can be used to measure the ratio of bacteria with respiratory activity to total bacteria on the analysis of the fluorescent images from each stain.

Low melting Agarose is a low melting temperature agarose with the highest resolving capacity for large DNA/RNA fragments, including PCR product. Low melting temperature allows for the recovery of undamaged nucleic acid below denaturation temperature. Low gelling temperature ensures in-Gel applications can be performed in remelted agarose.
