DBCO-PEG4-PABA is an analog of DBCO-Acid with PEG linker and a 4-Aminobenzoic acid (PABA) group. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility. Reagent grade, for research use only.

The Digestible and Resistant Starch Assay Kit (K-DSTRS) for the determination of digestible, resistant and total starch in starch samples, plant and other materials.
This method is based on the research of Englyst et al. (Ref) with some modifications. Digestion is performed using saturating levels of pancreatic α-amylase (PAA) and amyloglucosidase (AMG), but in stirred containers rather than shaken tubes, to simplify sample removal.
In line with Englyst definitions:
Rapidly digestible starch (RDS) is that starch which is digested within 20 min.
Slowly digestible starch (SDS) is that starch which is digested between 20 and 120 min.
A new term, ‘Total digestible starch (TDS)’ is introduced (and measured) to cover all starch that is digested within 4 h (the average time of residence of food in the human small intestine).
Resistant starch (RS) then, is that starch which is not digested within 4 h.
The incubation conditions parallel those used in AOAC Method 2017.16, a new, rapid integrated procedure for the measurement of total dietary fiber (Megazyme method K-RINTDF). This method is physiologically based and designed to fit the definition of DF announced by Codex Alimentarius in 2009.

AZtaq™ DNA Polymerase is a high-quality DNA polymerase, originating form Thermus aquaticus. Being highly thermostable, AZtaq is ideal for use in polymerase chain reaction (PCR) applications.
The enzyme catalyses the synthesis of a complementary DNA strand using a primed DNA or cDNA strand as template. It possesses 5’-3’ exonuclease activity while lacking 3’-5’ proofreading activity.
AZtaq is compatible with the use of dUTP, enabling highly efficient removal of carry-over contamination with Cod UNG.
Quality Control
ArcticZymes is dedicated to the quality of our products. AZtaq is manufactured at our ISO 13485 certified facility in Norway.

This Kit is designed to purify genomic DNA and total RNA simultaneously from a single biological sample. Lysate is first passed through a DNA spin column to selectively isolate DNA and then through an RNA column to selectively isolate RNA. Pure DNA and RNA are purified from the entire sample, in contrast to other procedures where either the biological sample or the purified total nucleic acids is divided into two before being processed separately. The kit is compatible with small amounts of a wide range of animal cells and tissues.

The Kits are designed to purify both genomic DNA and total RNA from the same cellor tissue sample. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column and bind DNA. Ethanol is added to the flow-through and the sample is applied to an RNA column. DNA/RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit. High-quality DNA is eluted in as little as 50µl water using the Kit.

Storage and Stability
HiPure DNA/RNA Kit can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. Make sure that all buffers are at room temperature when used. During shipment, crystals or precipitation may form in the Buffer RLC. Dissolve by warming buffer to 37°C.
