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.

Product Description
【Principle Overview】
This kit is based on a rapid nucleic acid amplification technology at room temperature and constant temperature: at room temperature and constant temperature (generally 39℃~42℃), with the help of auxiliary proteins and single-strand binding proteins, the recombinase and primers form a complex; Source search and combine the target homology domain, at this time, a D-loop region is formed at the homology position and strand exchange begins; along with the dissociation of the recombinase from the complex, the polymerase also binds to the 3′ end of the primer and begins chain extension. Relying on the action of nfo enzyme, adding specific molecular probes designed according to the template, and using colloidal gold technology (sandwich method) can detect the final result.
【Primer design】
It is recommended to use primers with a length of 30-35 bp.Too short primers will affect the amplification speed and detection sensitivity;the 5′ end of the reverse primer is labeled with a modification group (commonly used biotin).
Primers are designed to avoid the formation of secondary structures that affect amplification; the length of the amplicon is recommended to be 150-500bp.
【Colloidal gold probe design】
In the middle of the forward and reverse primer,design a sequence of 46-52nt in length that is complementary to the target fragment; modify an antigen marker (typical FAM) at the 5′ end;mark a dSpacer (tetrahydrofuran, THF) in the middle of the 5′ end and the 3′ end ), as the recognition site of nfo;the 3′ end is labeled with a modification group, such as amine group, phosphate group or C3-Spacer, etc.
【Features】
This kit has the advantages of high sensitivity, strong specificity,and short reaction time (only 15 minutes),and the reaction components are in dry powder state,which is easy to operate and easy to store.
This reagent has low equipment requirement,and the reaction operation can be carried out in metal baths, water baths, etc.,and there is no need to purchase expensive exclusive equipment such as PCR amplifiers.

Storage Conditions
The Legionella sp. TaqMan PCR Kit Dx is shipped on dry ice. The components of the kit should be frozen upon arrival. If one or more of the components is not frozen when the kit is received, or if any of the components have been compromised during shipment, please contact Norgen Biotek for assistance. All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 3 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.
