Propargyl-PEG4-NHS ester is an amine reactive PEG linker with an alkyne group. Under the copper catalyzation, alkyne group can react with azide-bearing biomolecules to form a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s EXTRAClean Urine Cell-Free Circulating RNA Purification Kits provide a fast, reliable, reproducible, and simple procedure for isolating circulating RNA and exosomal RNA from various urine inputs ranging from 250 μL and up to 30 mL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real-time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extensions, and expression array assays.
EXTRAClean Cell-Free Circulating RNA Purification Mini Kit: For sample volumes ranging from 250 μL to 2 mL
EXTRAClean Cell-Free Circulating RNA Purification Midi Kit: For sample volumes ranging from 2mL to 10mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL
EXTRAClean Cell-Free Circulating RNA Purification Maxi Kit: For sample volumes ranging from 10 mL to 30 mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. These kits are stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Fourteen discrete fragments ranging from 25 bp to 650 bp in 50 bp increments
Double intensity reference bands at 200 bp and 400 bp
The Norgen MiniSizer 50 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. This Ladder contains fourteen discrete fragments ranging from 25 bp to 650 bp in 50 bp increments with double intensity reference bands at 200 bp and 400 bp. The MiniSizer is ideal for PCR product size confirmation.
Contents:
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).
MiniSizer 50 bp DNA Ladder (Cat# 11200) – 100 loads
Ladder Properties: • Fourteen discrete bands, ranging from 50 bp to 650 bp • Higher intensity bands at 200 bp and 400 bp for easy reference

Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
Our SNPsig® kits use our own proprietary genotyping method to enable the identification of SARS-CoV-2 variants of concern. These products can be used on any real-time PCR machine using familiar protocols, whilst resulting in exceptional genotyping data.
Positive control templates for wild-type and variants are supplied in every kit to make data interpretation simple.
Our SNPsig® technology provides an alternative to sequencing as well as S gene target failure (SGTF) that enables scientists to analyse and monitor these specific genomic mutations. Our kits can provide a pivotal role in screening for SARS-CoV-2 variants for the purpose of genomic surveillance and studies.
