Clostridium difficile is rod-shaped, gram positive bacterium. It is the main causal agent of antibiotic-associated diarrhea and pseudomembranous colitis. The colonization of intestines by C. difficile is usually associated with the elimination of natural intestinal flora as a result of antibiotic application and is frequently reported in health care centers. While C. difficile infection could be severe and life-threatening, particularly among the elderly, many patients are asymptomatic making diagnosis challenging during outbreaks. The tradition method of detecting C. difficile infection is by cytotoxicity test of the toxin produced by the bacterium, but such protocols usually require extensive time before conclusion can be made.

Twenty 4.5X60mm strips of each combination of nitrocellulose (4X), wicking material (2X), and sample pad (3X)
Blank lateral flow strips are the perfect companion during the development and feasibility testing of a lateral flow device. IN THE BEGINNING, the capture and test line reagents can be spotted onto the nitrocellulose portion of the blank strips at different concentrations, volumes and buffer conditions. This enables the user to determine the optimal conditions for subsequent spraying and enables the user to verify the test and controls will respond according to expectations before scaling up the process.
These blank strips are compatible with all of our colloidal gold products AND:
Lateral flow cassettes: C02022
Streptavidin CdSe/ZnS Quantum Dots For Lateral Flow: AU2043

Twenty 4.5X60mm strips of each combination of nitrocellulose (4X), wicking material (2X), and sample pad (3X) A total of 480 strips are provided 100 cassettes 125mL of buffer
NGS Library Quantification Standards With PCR Primers

Product Info
The NGS Library Quantification Standards with PCR Primers (for illumina platform) were developed for quantification of the NGS library concentration for illumina sequencing platform. It is comprised of Library Standards (six 10-fold dilutions) and a primer mix.
Quantification of the NGS library of the amplifiable molecules is critical for the quality of the sequencing data. Adequate library concentration will maximize sequencing capacity. Poor library concentration results in either low or high cluster density on the flow cell, which can lead to low sequencing capacity.
It is not accurate to measure the concentration of NGS library with standard DNA quantification methods such as spectrophotometer or fluorometer. QPCR is the best way for library quantification with high consistency and reproducibility of library quantitation.
BioDynami Library Quantification Standards with PCR Primers (for illumina platform): Amplification curve of 6 standards.
Our reagent is a highly sensitive, Real time PCR-based quantification that specifically designed for NGS libraries using illumina sequencing platform. The amplification uses illumina adaptor sequences as primers, and only the fully adaptor-ligated libraries will be amplified. Therefore the reagent provides an accurate estimation of the library concentration based on true sequenceable illumina libraries. In addition, this kit can also be used for confirmation of ligation reaction after completion of library preparation.
Our library quantification standards is compatible with commercial SYBR Green based QPCR reagents. This makes it more flexible for scientists who want to use their real time PCR reagent. Quantification of library concentration is achieved by comparison with a standard curve generated from the Library Standards.

Product Info
Overview
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias
Versatile sample input ranges
Isolate all sizes of free-circulating RNA, including microRNA
Bind and elute all RNA irrespective of size or GC content, without bias
The purified exosomal RNA is free from any circulating RNA-binding proteins
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
Concentrate isolated exosomal RNA and free-circulating RNA into a flexible elution volume ranging from 50 µL to 100 µL
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provide a fast, reliable and convenient method to sequentially isolate and concentrate exosomal RNA as well as Free-Circulating 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 since they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. 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 shipping. 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.
