Introduction

This product uses an improved salt precipitation purification method to provide a safe and economical solution for High Weight genomic DNA extraction from blood samples, tissue samples, cultured cells, oral swabs, bacteria, and other samples. The extraction does not require the use of toxic phenol chloroform or any expensive reagents, making it the most economical reagent kit for nucleic acid extraction at present. This kit has no limit onthe amount of sample used and can flexibly adjust various amounts of samples. The obtained DNA can be directly used for experiments such as PCR, enzyme digestion, Southern hybridization, and the Third-generation sequencing.

Principles

SolPure DNA Kits is an improved salt precipitation purification method. (Blood samples are lysed in red blood cell lysis buffer to remove red blood cells, and white blood cells are collected by centrifugation.) After lysis, DNA is released into the lysis buffer. RNA is removed by RNASE A. High salt solution is added to precipitate proteins and impurities. Centrifuge to remove precipitate and obtain supernatant containing only DNA. Add isopropanol to precipitate and recover DNA. Wash with 70% ethanol to remove salt, and finally add Buffer TE to dissolve DNA.

Storage and Stability

RNase A and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 4 weeks) at room temperature (15–25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

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

Overview

• Detection kits for Clostridium difficile
• CE-IVD marked version available for in vitro diagnostic use
• Available in TaqMan format for analysis

Clostridium difficile is rod-shaped, gram positive bacterium. It is the main causal agent of antibiotic-associated diarrhea and pseudomembranous colitis. The colonization of intestines by C. difficile is usually associated with the elimination of natural intestinal flora as a result of antibiotic application and is frequently reported in health care centers. While C. difficile infection could be severe and life-threatening, particularly among the elderly, many patients are asymptomatic making diagnosis challenging during outbreaks. The tradition method of detecting C. difficile infection is by cytotoxicity test of the toxin produced by the bacterium, but such protocols usually require extensive time before conclusion can be made.

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.
