SKU: 700004326

100 assays (manual) / 400 assays (auto-analyser)

The Phosphate Assay Kit is a rapid, simple, reliable and accurate method for the specific measurement and analysis of phosphate in water, foodstuffs, beverages and other materials. The phosphate detection reaction employs the defined chemical substrate 2-amino-6-mercapto-7-methylpurine ribonucleoside (MESG). In the presence of phosphate, the substrate is converted enzymatically by purine nucleoside phosphorylase (PNPase) to the products ribose 1-phosphate and 2-amino-6-mercapto-7-methylpurine. An application note describes the dephosphorylation reaction of phytic acid using phytase and alkaline phosphatase (sold separately), and subsequent phosphate detection using the reagents provided in K-PHOS.

This method is suitable for analysis using spectrophotometer and auto-analyser.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.

Description 

The ExcelRT™ Reverse Transcriptase is a recombinant Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase – an RNA dependent DNA polymerase capable of generating first strand cDNA using an RNA template. It is designed to reduce RNase H activity and create better thermal stability. The ExcelRT™ Reverse Transcriptase is able to routinely synthesize first strand cDNA >8 kb at 37~50°C.

Features

• High yield
• Thermostable, up to 50°C, during first strand synthesis
• High processivity, generating cDNA up to 8 kb
• Reduced RNase H ribonuclease activity

Application

• Generation of first strand cDNA from total RNA or mRNA.
• Suitable for generating cDNA from RNA with strong secondary structure which can be reduced at temperature up to 50°C.

Storage
