Usages: For cultivations of yeasts , moulds and acidophilic bacteria.
Principle: Peptone and yeast extract powder provides carbon and nitrogen sources and trace elements; lactose are fermentable sugars; sodium chloride maintains osmotic equilibrium; the 3rd bile salts and crystal violet inhibiting gram-positive bacteria, especially against Gram positive bacteria and fecal streptococci; neutral red as pH indicator.
How to use: 1.Suspend 30g in 1 L of distilled water , stirring heated to boiling until completely dissolved, dispensing flask, 121 ℃ autoclave for 15min. 2.Diluted and treated samples.

Product Info
Description
The DM2360 FluoroBand™ 100 bp+3K Fluorescent DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with high sensitivity DNA binding fluorescent dye and loading dye for direct gel loading. The DNA Ladder DM2360 is composed of 12 individual DNA fragments: 3k, 1.5k, 1k, 900, 800, 700, 600, 500, 400, 300, 200 and 100 bp derived from a mixture of PCR products and specifically digested plasmid DNA; these bands can be visualized when illuminated with 470 nm blue light or UV light. This product contains two enhanced bands (1.5 kb and 500 bp) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Orange G which mimic the migration of 4,000 bp and 50 bp dsDNA during electrophoresis are also added for real time monitoring. Real time observation of the electrophoresis is also possible if compatible light source is fitted to the electrophoresis tank.

Quantify RNA of a wide spectrum of concentrations, including the lower ng per µL and pg per µL range
Compatible with any Real-Time PCR system
RNA is accurately quantified using a standard curve constructed from the provided RNA standard
Norgen’s Low Abundance RNA Quantification Kit offers a PCR-based detection procedure to quantify RNA of a wide spectrum of concentrations, including the lower ng per µL and pg per µL range. The kit has two main enzymatic components – reverse transcription using Norgen’s microScript Reverse Transcription system and PCR Master Mix used in conjunction with a specially formulized primer mixture, to amplify human RNA from different types of inputs (such as various liquid biopsies). The kit is compatible with any Real-Time PCR system with the addition of fluorescent nucleic acid stains such as SYBR Green. The unknown RNA is accurately quantified by using a standard curve constructed from the provided RNA Standard.
Storage Conditions Upon receipt, store Norgen’s Low Abundance RNA Quantification Kit at -20°C or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20°C or lower.
The ExcelRT™ One-Step RT-PCR Kit is designed for the reverse transcription and PCR amplification of a specific target RNA from either total RNA or mRNA. The ExcelRT™ One-Step RT-PCR Kit provides the user an alternative to the lengthy two step processes (first strand generation and amplification) by using a single mixture, single tube, one step reaction. The ExcelRT™ One-Step RT-PCR Kit contains a 2X reaction premix consisting of an optimized buffer, dNTPs, Mg2+ and enzyme stabilizer, and a blend of recombinant reverse transcriptase and Taq DNA polymerase. The ExcelRT™ One-Step RT-PCR Kit allows the user to complete the RT-PCR process using a thermocycler in a single reaction setting. The ExcelRT™ One-Step RT-PCR Kit is capable of detecting even trace amounts of target RNA and ideal for target RNA amplification and analysis.
