Formaldehyde is an organic compound with the formula CH2O. It is mainly used in the production of industrial resins but has been found to be used as a preservative, disinfectant and biocide. Because of its toxicity and volatility formaldehyde poses a significant risk to human health. Attogene test uses the property of formaldehyde to react with the Formaldehyde Reaction Powder (FRP) to form a purple-red tetrazine. The formaldehyde concentration is measured by visual comparison of the reaction with the color scale derived from the Color Card.

The dsDNA Quantification Broad Range Kit and dsDNA Quantification High Sensitivity Kit are developed for double stranded DNA quantification using microplate readers. The DNA Quantification BR kit includes BR Dye, BR Dilution Buffer, and BR DNA Standards. The DNA Quantification HS kit includes HS Dye, HS Dilution Buffer, and HS DNA Standards. Simply dilute the Dye with the Dilution Buffer, add DNA sample, then read the concentration using microplate reader. The BR assay is accurate in the linear range from 4 to 1000 ng and the HS assay is accurate in the linear range from 0.2 to 100 ng. Both kits are highly selective for double-stranded DNA over RNA.
The Quantification Kits have several advantages over traditional DNA quantitation such as sensitivity, stability, and tolerance of contaminants.
Both kits reduce the cost of DNA quantification by 60% as compared to other brands.
Selectivity and sensitivity of the kits
Save 60% of the costs.
The performance of the kit is nearly identical to that of Thermo Fisher’s kit (figure below).

Common contaminants such as salts, free nucleotides, solvents, detergents, RNA, single stranded DNA, or protein are well tolerated in the assay (Table 1).
The DM2300 ExcelBand™ 100 bp+3K DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA ladder DM2300 is composed of 12 individual DNA fragments: 3k, 1.5k, 1k, 900, 800, 700, 600, 500, 400, 300, 200 and 100 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (1.5 kb and 500 bp) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Orange G which mimic the migration of 4,000 bp and 50 bp dsDNA during electrophoresis are also added for real time monitoring.
