Aminooxy-PEG3-propargyl has a alkyne group and an aminooxy group. The aminooxy group reacts with aldehydes or ketones to form a stable oxime linkages. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Megazyme’s catalase assay kit provides a simple colourimetric method for the measurement of catalase activity. The method is delivered in a fast and reliable format and may be used to detect catalase activity in various samples, including food, biological and bacterial samples. The calculation method included allows for significant variation in the concentration of the H2O2 substrate solution that is employed in the assay which translates into a reduction in the ‘hands on’ time required by the analyst in comparison to other commercial kits.
See our complete list of assay kits for the measurement enzyme activity.
Advantages
Very cost effective
Simple, convenient, rapid assay
Standard included
Mega-Calc™ software tool is available from our website for hassle-free raw data processing

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.

Neisseria gonorrhoeae is a Gram-negative coccus of the Neisseria genus. N. gonorrhoeae is usually seen in pairs infecting human cells. It has a circular DNA genome of approximately 1Mbp encoding over 2000 genes. N. gonorrhoeae is transmitted by sexual contact and usually causes infection in cells of the mucous membrane of the male urethra or the endocervix and urethra in females. During infection, polysaccharides are released from the bacteria that stimulate host cell production of tumour necrosis factors that cause an inflammatory response.
There is no vaccine against N. gonorrhoeae infection and antibiotic resistance is beginning to increase, therefore treatment includes a course of antibiotics that will be effective against resistant strains. Complications in males caused by the infection can result in prostatitis or orchitis if the bacteria spread. In females, invasion of the fallopian tubes or ovaries can result in salpingitis or ovaritis respectively, with any of these infections possibly resulting in sterility.
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.
