Method recognition:
Improved method
The Acetic Acid GK format test kit is for use with auto-analysers and is suitable for the specific measurement and analysis of acetic acid (acetate) especially in wines, fruit juices, beverages and food products.
As part of Megazyme’s overall commitment to providing the highest quality products, we have developed this acetic acid kit that provides a specific and rapid assay for use with auto-analysers. The kit assay is based on the conversion of NAD+ to NADH and therefore provides a positive reaction (increase in absorbance) which offers a more robust assay.
The reagents, as supplied, are stable for a minimum of 2 years and the prepared reagents are stable for a minimum of 1 week (on-board stability). In addition, the prepared reagents can be stored frozen for longer term stability (see K-ACETGK Booklet for more details).

Excellent reagent stability
> 7 days at 4oC or > 2 years below -10oC when prepared for auto-analyser applications
> 2 years as supplied
Very rapid reaction (~ 5 min at 37oC)
Linear calibration (R2 ~ 0.997 up to 1.8 g/L sample)

Attogene Fluorescent UniversalLateral Flow Assay Kits are a convenient ready-to-use kit for quick and cost-effective development of a fluorescent lateral flow dipstick assay for detection of DNA and RNA products.
Fluorescent lateral flow assays can be 2-100 fold more sensitive that gold based lateral flow tests.
Formats (fluorescent broad range UV light excitation range of 100nm to 400nm, 655nm emission) Streptavidin conjugate pad):
• Detectable using a black light such as a black light UV flashlight or fluorescent lateral flow reader.
• Detection of nucleic Acid (DNA or RNA) requires the use of a biotin and FAM-labelled primer during amplification.
• Test line: anti-FITC/FAM
• Control Line: Biotin
• Multiplex detection of nucleic Acid (DNA or RNA) requires the use of a biotin, FAM and Dig labelled primers during amplification.:
• Test Line #1: anti FITC/FAM, Line #2: anti-Dig, Line #3 Biotin.
For example, this product can be configured with alternative/custom streptavidin fluorescent particles.
Kit Components
50 -4.5mm Fluorescent Lateral Flow Dipsticks
10 mL Sample assay running buffer
Features & Benefits
Can be used for development of a lateral flow assay for detection of a variety of different molecules such as amplified DNA products from PCR, LAMP and RPA reactions.
No need to stripe capture antibodies
No expensive equipment required (Black Light)
Cost-effective way to screen for further downstream lateral flow assay development.
HL-dsDNase is especially developed to remove contaminating genomic DNA from RNA preparations. Figure 1 shows that HL-dsDNase can reduce 50 ng of human gDNA to levels non-detectable by qPCR. In figure 2, a human total RNA sample was treated with HL-dsDNase and analysed on the Bio-Rad Experion™ System. The results indicate that HL-dsDNase has minimal impact on RNA quality and quantity.
HL-dsDNase is an engineered version of dsDNase that is rapidly and completely inactivated by incubation for 5 minutes at 58°C with 1 mM DTT at pH 8.0 or above. Chemical inactivation in downstream compatible RT or PCR buffers allows milder heat inactivation and, in some cases, skipping heat inactivation altogether. This makes HL-dsDNase very useful for removal of DNA from RNA preparations since the enzyme may be inactivated using various strategies with reduced risk of auto-degradation of RNA in the presence of magnesium, making HL-dsDNase an ideal enzyme when working with small volumens of RNA.
HL-dsDNase is also an excellent choice for removal of unwanted external DNA from samples prior to analysis of nucleic acids protected by biological membranes, e.g., bacteria, viruses, and sperm. Especially if using downstream analysis methods that might be affected by host cell DNA, as metagenomic sequencing and STR-profiling. The easy inactivation of HL-dsDNase makes it a fast and efficient alternative to methods as differential extraction, where sample material is often lost.
Easily heat-inactivated by very moderate heat treatment
High specific activity
Useful for removal of DNA from RNA preps
