DBCO-PEG36-TFP ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The hydrophilic PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules. The TFP ester is less susceptible to undergo hydrolysis compared to the NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

All kit components should be stored at -20°C upon arrival.
Once reconstituted, repeated thawing and freezing (>2 times) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
EXTRAClean Urine Exosome Purification and RNA Isolation Kits

Product Info
Overview
Ensure optimal results for sensitive applications like NGS
Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
Purification and enrichment of intact urinary exosomes for functional studies.
Bind and elute all RNA irrespective of size or GC content, without bias.
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
No phenol extractions, Proteinase K treatment, nor carrier RNA required.
No time-consuming ultracentrifugation, filtration nor special syringes are required.
No precipitation reagents nor overnight incubation required.
Compatible with urine from any species.
Pure exosomes are purified and are free-from any other RNA-binding proteins.
Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary resin separation matrix.
Norgen’s EXTRAClean Urine Exosome Purification and RNA Isolation Mini Kit constitutes an all-in-one system for the purification of exosomes and the subsequent isolation of RNA from different urine sample volumes ranging from 250 μL to 1 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does 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, NGS application, 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.
Organophosphate compounds (OP) account for the largest class of rural and urban poisons in the world that are used to kill pests but can also be toxic to humans. OPs cause toxicity by means of blocking the acetylcholinesterase enzyme (AchE). The AChE-directed OPs react with a serine residue that is located at the catalytic site found within the AChE gorge. The OP targeted enzyme is no longer able to hydrolyze ACh, resulting in the buildup of ACh in the nerve synapse. This effect causes excessive excitation of the nerves, producing uncoordinated movements, tremors, paralysis and death. Both synthetic and natural(Guanitoxin) organophosphates are dangerous to humans — exposure can lead to visual, coordination, muscular, and neurological deficiencies, and in some cases even to death. In turn, exposure to OP is a significant public health concern which would significantly benefit from an improved detection platform.
Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples. For solid samples a simple sample preparation method is performed. The ability to detect Organophosphate is performed is simple and sensitive. The reaction uses a chromophore that can be detected by eye. In the presence of Organophosphate, the rate of chromophore production is reduced in a concentration dependent fashion. The higher the concentration of Organophosphate the less color is produced.
