N-(Amino-PEG1)-N-bis(PEG2-propargyl) HCl salt is a crosslinker consisting of an amino group with two propargyl groups. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by infection of various bacteria. Streptococcus dysgalactiae, a Lancefield group C α-hemolytic gram-positive bacteria, is a common pathogen in subclinical and clinical mastitis causing substantial economic losses in dairy herds. Streptococcus dysgalactiae has been isolated from infected mammary glands and teat injuries and is transmitted primarily during milking. However, detection of S. dysgalactiae in other cow tissues such as tonsils, mouth and vagina, and occurrence of S. dysgalactiae mastitis during the non-lactating period in herds, suggests that the organism also behaves as an environmental pathogen.

Norgen’s Exosome Purification and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the subsequent isolation of exosomal RNA from different urine sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The purified RNA is free from any protein-bound circulating RNA and of the highest integrity. The purified RNA 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.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Important Note
Urine samples stored at -70°C, -20°C or at 4°C will develop some precipitation due to the aggregation of some of the highly abundant proteins in urine. Eliminating these precipitates using centrifugation or filtration may cause the loss of exosomes. Furthermore, these precipitates may affect the quality of the purified nucleic acid. We recommend the use of Norgen’s Urine Preservative when collecting urine samples, which is designed for the preservation of nucleic acids and proteins in fresh urine samples at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins. Norgen’s Urine Preservative is available as a liquid format in Norgen’s Urine Preservative Single Dose Ampules, as well as in a dried format in Norgen’s Urine Collection and Preservation Tubes.

Solid Phase Adsorption Toxin Tracking (SPATT) is a biomimetic in-situ water monitoring tool that falls under an expanding umbrella of passive samplers. It serves to warn researchers of toxin-producing harmful algal bloom (HAB) developments early on. It has been popularized through its affordability, ease of use, and its ability to capture ephemeral events in marine, brackish, and freshwater environments. Its uptake of contaminants has been shown to be more similar than other sampling methods to that of aquatic species like bivalves, mussels, and clams. It provides an average bioavailable fraction of a toxin over deployment time that can be used to determine an overall toxin risk to organisms. The sampling period typically depends on the bioactivity at a site, ranging from 24 hours to 4 weeks in most cases.
A SPATT passively absorbs and desorbs extracellular compounds over its stretch of time at a sampling site; in an organism, a toxin would go through biochemical detoxification processes. Passive samplers have a higher sensitivity for more compounds and provide improved stability and preservation of these compounds within the resin. SPATT devices capture less commonly detected cyanotoxins (e.g. cylindrospermopsin) at lower concentrations than that of a grab sample (collected at one point in time). Grab samples are limited in scope and sensitivity, and underrepresent toxins like microcystin-LR, which is picked up very reliably through SPATT technology.
Uses HP20 that is widely applicable for many toxins.
