DBCO-STP Ester is an amine-reactive, water-soluble labeling reagent, including a DBCO group for click reactions with azide groups on target molecules and an STP ester group, which can react with primary amines, forming covalent amide bonds. STP esters typically display much better stability toward hydrolysis in aqueous media, resulting in more efficiency and better reproducible labeling of biopolymers. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s cf-DNA/cf-RNA Preservative Tubes Dx are closed, evacuated plastic tubes for the collection and the preservation of cf-DNA, circulating tumor DNA, cf-RNA and circulating tumor cells in human whole blood samples during storage and shipping. Using these tubes in combination with Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits or Norgen’s Plasma/Serum RNA Purification Kits enables the purification and concentration of an inhibitor-free cf-DNA/ct-DNA/cf-RNA in a very small elution volume.
These tubes are ideal for collecting and preserving cf-DNA and cf-RNA samples for in vitro diagnostic use for medical purposes.
Performance
Norgen’s cf-DNA/cf-RNA Preservative Tubes Dx abridge the collection/processing of whole blood for the subsequent purification of cf-DNA and/or cf-RNA. The cf-DNA/cf-RNA Preservative Tubes Dx preserve and inhibit the programmed cell-death (apoptosis) of the blood, hence preventing the release of intracellular DNA/RNA into plasma. Whole blood samples can be shipped and stored at room temperature for the subsequent processing of plasma. The cf/ct DNA and cf-RNA levels are stable for up to 30 days at room temperature. The cf-DNA is also stable for up to 8 days at 37°C.

Storage Conditions and Product Stability
When stored at 15-30°C, unfilled Norgen cf-DNA/cf-RNA Preservative Tubes Dx are stable through the expiration date. See tube label for expiry date.
Short-term storage/shipping at -20°C to 37°C for up to 10 days is acceptable for unfilled Norgen cf-DNA/cf-RNA Preservative Tubes Dx.
Do not freeze unfilled Norgen cf-DNA/cf-RNA Preservative Tubes Dx for long term storage over 10 days. Freezing unfilled tubes may lead to loss of vacuum and precipitation may occur.

Norgen’s microScript microRNA cDNA Synthesis Kit is an all-in-one, ready-to-use product for the reverse transcription of microRNA from either Total RNA preparations or enriched microRNA preparations. The kit contains the 2x Reaction Mix and the microScript microRNA Enzyme Mix. The kit utilizes Norgen’s microScript Reverse Transcriptase, a mutant version of Moloney Murine Leukemia Virus (M-MuLV) Reverse Transcriptase. It has reduced RNase H activity and increased thermal stability.
The workflow of Norgen’s microScript microRNA cDNA Synthesis Kit involves a simple, single-tube set-up by the mixing of 2x Reaction Mix, Enzyme Mix and the RNA template. The reaction can then be carried out in a thermocycler. A poly (A) tail is first added to the RNA template, followed by cDNA synthesis using an adapter primer. In addition to the ease-of-use, the single-tube set-up provides superb consistency and sensitivity. The cDNA could be used in a PCR or qPCR amplification using a Universal PCR Reverse Primer and the forward primer that contains the sequence of the microRNA of interest. A single cDNA preparation could be used for PCR amplification of a number of different microRNAs. In addition, the cDNA preparation could be used for PCR or qPCR detection (using gene-specific forward and reverse primers) of mRNA or large RNA if total RNA preparation was the starting template. This could allow for parallel evaluation of expression level of microRNAs and microRNA-targets.
Storage Conditions and Product Stability Norgen’s microScript microRNA cDNA Synthesis Kit components should be stored at -20°C. These reagents should remain stable for at least 1 year in their unopened containers.
