DBCO-PEG24-TFP ester is a heterobifunctional PEG linker with an azide-reactive DBCO and an amine-reactive TFP ester that is less susceptible to hydrolysis than an NHS ester. The PEG linker improves the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit. Details of the target and priming specificity are included in the individual handbooks above.

Attogene’s Microcystin Test Kit (Rapid – Drinking Water) can be used to detect microcystins in water to as low as 0.1ppb; highly sensitive, rapid, robust screening kit for microcystins and nodularins.
The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.
A tiered notification system which takes different actions based on thresholds for microcytin-LR concentrations in drinking waters has been developed. This is guidance that allows states to take various actions.
For the rapid screening of microcystins in drinking water samples at or above 0.1 ppb. Samples requiring regulatory action should be confirmed by ELISA, HPLC, or other conventional methods.
To protect consumers from adverse health effects caused by these toxins, the World Health Organization (WHO) has proposed a provisional upper limit for Microcystin-LR of 1.0 ppb (μg/L) in drinking water.
The U.S. Environmental Protection Agency (EPA) has also established guidelines for Microcystins in drinking water:
-For children below school age, 0.3 μg/L (ppb)
-For all other age groups, 1.6 μg/L (ppb)

Norgen’s Plant/Fungi Total RNA Purification Kit provides a rapid method for the isolation and purification of total RNA, including virus and viroid RNA, from a wide range of plants. Total RNA can be purified from fresh or frozen plant tissues, plant cells or filamentous fungi samples using this kit. All sizes of RNA are purified, including microRNA (miRNA) . The procedure is rapid and convenient.
The RNA is purified without the use of phenol or chloroform. The purified RNA is of the highest quality, and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
Norgen’s Plant/Fungi Total RNA Purification Kit is also available in a 96-well (High Throughput) format for high throughput applications. Purification with the 96-well plates can be performed using either a vacuum manifold or centrifugation.
