N-(Propargyl-PEG4)-N-bis(PEG4-acid) is a branched crosslinking reagent with a propargyl group and two terminal carboxylic acids. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acids can react with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

For plate-based colorimetric enzymatic determination of alkaline phosphatase:
Distributed in almost every tissue of the body, serum alkaline phosphatase (ALP) levels are of interest in the testing for hepatobiliary disorder and bone disease. Most of the ALP in the normal adult serum is from the liver or biliary tract. Normal alkaline phosphatase levels are age-dependent and are elevated during periods of active bone growth. Moderate elevations of ALP (not involving the liver or bone) may be attributed to Hodgkin’s disease, congestive heart failure, and abdominal bacterial infections.
Alkaline phosphatase (ALP) catalyzes the hydrolysis of phosphate esters in an alkaline environment, resulting in the formation of an organic radical and inorganic phosphate. In mammals, this enzyme is found mainly in the liver and bones. Marked increase in serum ALP levels, a disease known as hyperalkalinephosphatasemia, has been associated with malignant biliary obstruction, primary biliary cirrhosis, primary sclerosing cholangitis, hepatic lymphoma, and sarcoidosis.
The kit contains sufficient materials to rapidly test 42 samples in duplicate.

Highly Sensitive, rapid, robust screening kit for sample phosphatase activity.
Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.
Packaged, optimised and ready to use. Expect Better Data.

Campylobacter jejuni is a curved, rod-shaped and microaerophillic gram negative bacterium. It is one of the most common causal agents of gastroenteritis with diarrhea as the main symptom. While infection of C. jejuni is seldom life-threatening, it is considered one of the most common food-borne bacteria with over 2 million people infected per year in US alone. Infection of C. jejuni usually results from consumption of poorly prepared food including undercooked meat (particularly poultry), untreated water or raw unpasteurized milk. Traditional identification of C. jejuni involves culturing, however the microaerophilic characteristic of this bacterium make the enrichment process laborious and costly.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
