Highly Sensitive Assay to Screen for Benzoic Acid Visual Readout (sample dependent: milk, red/pink) Detection range of 1ppm to 1500ppm Tube or Plate based options available Compatible with the Nix Sensor or plate readers to obtain quantitative results.
The Benzoic Acid Detection Kit provides a rapid, simple, sensitive, and reliable test suitable for screening of Benzoic Acid concentration.
Benzoic Acid is a white solid that is an extensively used preservative. Although this preservative prevents or delays nutritional losses due to microbiological, enzymatic or chemical changes of foods during its shelf life there is a suspicion that small amounts of benzene may be formed from benzoic acid in nonalcoholic beverages in the presence of ascorbic acid. Benzoic acid and ascorbic acid are food additives which must be declared on the food. Benzoic acid or E 210 is a preservative which also occurs naturally, for instance, in cranberries. A maximum amount of 150 mg/l benzoic acid may be added to non-alcoholic flavored beverages.

Description
ExcelRT™ Reverse Transcription Kit II is a complete, efficient and convenient kit to synthesize high quality first strand cDNA. This kit contains ExcelRT™ Reverse Transcriptase, which is able to synthesize the first strand cDNA at 37~50°C. The ExcelRT™ Reverse Transcriptase is a recombinant Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase, which is designed to reduce RNase H activity and create better thermal stability. This kit also contains RNAok™ RNase Inhibitor, which is active against RNase A, RNase B, and RNase C. This product is supplied with optimized RT Buffer and Oligo (dT)/Random Primer Mix for highly efficient synthesis of short chain cDNA suitable for real-time PCR.
Features

Candida albicans is an opportunistic yeast and is the most common fungal pathogen found in the human body. C. albicans can be detected in the gastrointestinal tract, mouth, and vagina of approximately half of healthy adults. It is typically a commensal organism and makes up part of the natural human microflora; however it can overgrow and become pathogenic as a result of various conditions. For example, individuals who have taken recent courses of antibiotics, have a weakened immune system or have diabetes have an increased risk of developing a Candida albicans infection. When an overgrowth occurs, this can lead to common infections such as urinary tract infections, genital yeast infections, oral thrush, and mucocutaneous candidiasis. In the more severe cases, when Candida albicans enters the bloodstream or organs, it can lead to loss of sight, blood and bone infections, endocarditis, meningitis or inflammation of the intraabdominal lining.

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.
This kit is used for extracting total viral nucleic acid from non-cell/low cell content biological samples such as body fluid, serum, plasma, urine, immersion solution, tissue homogenate supernatant, culture supernatant, etc., the extracted products can be used for clinical in vitro detection.

Principle
This product is based on silica gel purification. The sample is lysed and digested with lysate and protease, DNA / RNA is released into the lysate. Transfer to an adsorption plate and filter column. DNA/RNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, DNA / RNA was finally eluted with low-salt buffer (10 Mm Tris, pH 8.0).
Advantages
Fast – several samples can be extracted in 20 minutes by column method
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Safe – no phenol chloroform extraction required
Sensitive – DNA/RNA can be recovered at the level of PG
High yield – carrier RNA contained in the product maximize the recovery of trace nucleic acid

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for 18 months under these conditions.
