Propargyl-PEG4-CH2CO2H is a linker consisting of a propargyl group with a carboxylic acid group. The carboxylic acid can react with primary amine groups in the presence of activators such as HATU or EDC. The propargyl group can react with azide compounds in Click Chemistry; copper catalyst will be needed. The PEG units help the molecule to have better solubility in aqueous solution. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
DirectBlood Genotyping PCR Kit is a novelty on the market. It allows genotyping in real-time and without any previous DNA isolation. You simply save time and money: directly use EDTA blood without any extraction steps. The DirectBlood Genotyping PCR Kit is optimized to function with a wide range of different SNPs to detect possible nucleotide variations. It has been successfully tested with a variety of hydrolysis probes and hybridization probes.The setup of a genotyping experiment can not be simpler anymore: Mix primers&probes with the Genotying mastermix, add the respective blood sample and start real-time PCR, this is it.
It is even more simple: store the DirectBlood Genotyping PCR Kit at room-temperature. A cool chain is not needed anymore. The included master mix is freeze-dried and dissolves within a few seconds after addition of the rehydration buffer.Additionally, we have already established SNP-assays for you. In case, you can not find your respective SNPs, please provide us with the rs-number of the SNP-assays your are interested-in and you will receive an individual quotation from us.For research use and further manufacturing.In case you are aiming to use our RUO products as components or for your development of e.g. an IVD medical device, please contact us.
DirectBlood Genotyping Kit (#5000) performance with a hydrolysis probe assay
The DirectBlood Genotyping Kit is compatible with a wide range of assays: Here we are detecting a SNP in the Factor V gene (rs6025; G1691A), which is connected with a higher risk for venous thrombosis, with a fluorescent hydrolysis probe assay.
Homozygous wild type blood samples will show a strong signal and amplification plot (blue curve) in channel 2 (Cy5) and none or a very low signal
(red curve) in the other channel 1 (ROX).
Heterozygous blood samples will give an intermediate signal and amplification plots with very similar intensities in both channels 1 and 2 (blue and red curve). Homozygous mutant blood samples, channel 1 (ROX) will show a strong signal and amplification plot (red curve) and channel 2 (Cy5) none or a very low signal and amplification plot (blue curve). So the signals are reversed on homozygous mutant samples.
DirectBlood Genotyping Kit performance with a hybridization probe assay
Here we are detecting the same SNP in the Factor V gene (rs6025; G1691A), which is connected with a higher risk for venous thrombosis, with a fluorescent hybridization probe assay.
Three blood samples with known genotype were used. All the genotypes can clearly be identified. The blue curve shows the specific wild type (homozygous G;G) peak at 61°C. The red curve shows the specific mutant (homozygous A;A) peak at 53°C. A heterozygous case (A;G) will result in both melting curve peaks, respectively at the same specific temperature for wild type and mutant (orange curve).

Purification and enrichment of intact urinary exosomes for functional studies
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
Versatile urine input volumes
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 most species
Pure exosomes are purified and are free from any other RNA-binding proteins
Purification is based on spin column chromatography that uses Norgen’s proprietary resin
The purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
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.
