PEG3-(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane)-(Amino-Tri-(endo-BCN-PEG2-ethoxymethyl)-methane) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The DBCO groups are commonly used for copper-free Click Chemistry reactions due to their strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility.

The L-Rhamnose Assay Kit for the measurement of L-rhamnose in plant extracts, culture media/supernatants and other materials is a simple, rapid method.
L-Rhamnose occurs naturally in the L-form and is commonly present as a component of the carbohydrate moiety of eukaryotic glycoproteins and in plant cell wall polysaccharides. The most abundant occurrence of L-rhamnose is within the pectic fraction of plant cell wall polysaccharides. L-Rhamnose is commonly used as a non-metabolisable marker along with lactulose for dual-permeability testing in the diagnosis of intestinal diseases such as Crohn’s disease or coeliac disease.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).

Norgen’s Urine DNA Isolation Kit for Exfoliated Cells or Bacteria is designed for the rapid isolation of either: 1) human genomic DNA from exfoliated cells that have been shed into the urine from the urinary tract; or 2) bacterial genomic DNA from urine samples. The kit allows for the isolation of DNA from 1 to 50 mL of urine. The genomic DNA isolated from exfoliated cells can be used in a number of diagnostic and research applications including the diagnosis and monitoring of bladder, kidney, or other urinary-tract cancers. Bacterial genomic DNA from both human urine samples and urine samples from animals can be isolated with this kit in order to study the levels and types of bacteria that are present. The kit allows for the isolation of genomic DNA from both Gram negative and Gram positive bacteria, including E. coli, Proteus spp., Klebsiella spp., Enterobacter spp., Serratia spp., Pseudomonas spp, Clostridial ssp. and Leptospirosis spp.Chlamydia trachomatis and Neisseria gonorrhoeae.
Typical yields of human genomic DNA from exfoliated cells will vary depending on the cell density of the urine sample, which is affected by a number of factors including health, diet and sex of the individual donating the urine. Typical yields of bacterial genomic DNA will vary depending on the urine sample and the bacterial species, if any, present in the urine. Healthy humans generally have < 10, 000 CFU of bacteria per mL of urine, and this kit is sufficiently sensitive to isolate and detect DNA from even this minimal amount of bacteria. The genomic DNA purified with this kit is fully digestible with all restriction enzymes tested, and is completely compatible with downstream applications such as PCR, qPCR and Southern Blot analysis.

LyoBeads are ready-to-use, freeze-dried master mixes in shape of a small ball or spheres.
Standard LyoBeads contain DNA polymerase(s), reaction buffer and dNTPs. LyoBeads can also contain Primer & Probes when produced customized. They are rehydrated within seconds in any aqueous solutions, which makes reaction setup very simple. Only a biological sample has to be added.
Storage: LyoBeads are shipped and stored simply at room-temperature. This provides a more cost efficient and ecological distribution compared to other master mixes.
LyoBeads can be pre-dispensed in PCR-strips, PCR-plates, cartridges etc.
All necessary components for PCR are already included in one LyoBead: an engineered DNA polymerase, an optimized reaction buffer and ultrapure dNTPs. Only primers and probes need to be added. A hot-start formulation of the included DNA polymerase prevents false amplification during the reaction set-up.
For research use and further manufacturing.
