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.

Both high molecular weight DNA (greater than 1 kb in size; mostly cell associated) and the smaller DNA (150 – 250 bp; derived from the circulation) is effectively isolated and purified using a rapid and convenient spin column protocol. This kit can be used to isolate DNA from a broad range of viruses in urine as well. Salts, metabolic wastes, proteins and other contaminants are removed to yield inhibitor-free DNA for use in sensitive applications. The DNA is of excellent quality for various downstream applications such as PCR, qPCR and DNA fingerprinting, methylation studies and more.
This kit is fully compatible with Norgen’s Urine Collection and Preservation Tubes.

Background
DNA found in urine can be divided into 2 basic categories. The larger species, genomic-DNA (gDNA), is generally greater than 1 kb in size, and appears to be derived mainly from exfoliated cells. The second species is smaller, generally between 150 and 250 bp (apoptotic-DNA), and derives, at least in part, from the circulation. The second species is also considered as an RNA/DNA hybrid as reported by Halicka et al. (2000). Both types of DNA can be isolated reliably using this kit.

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 up Slurry B1 and Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed. Slurry B1 contains a grey resin that will not dissolve when warmed.

These kits provide a convenient and rapid method for the isolation of microorganisms from water samples. The kits allows for the rapid isolation and purification of total RNA and DNA simultaneously from the microorganisms found in different types of water samples. The total RNA and DNA (including genomic DNA) are isolated from all the microorganisms found in the water, including bacteria, fungi and algae without the use of any inhibitory organic substances The kit purifies genomic DNA, and all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The purified RNA and DNA are highly concentrated, and can be used directly in a number of downstream applications including PCR, qPCR, RT-PCR, qRT-PCR, Northern blotting, Southern blotting and sequencing reactions.
Water RNA/DNA Purification Kit (Spin Column + Filters Kits)
These kits are available with 0.45 μm or 0.22 μm filter formats for capturing microorganisms present in the water.
Water RNA/DNA Purification Kit (Spin Column)
This kit is sold without filters columns.

The Acetic Acid (Acetate Kinase Manual Format) test kit is suitable for the measurement and analysis of acetic acid in food and beverages.
This rapid and reliable manual acetic acid kit is simple to perform (only two absorbance readings required), and because a true end-point is measured, does not involve complicated calculations like other kits. This product is very stable both during storage and use (> 2 years), has extended linearity (compared to ACS based kits), contains PVP to prevent tannin inhibition, and is performed at a relatively low pH (7.4), thus minimising ester hydrolysis related interference. This method is suitable for the measurement of acetic acid/acetate in foods, beverages and other materials.
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).
