Bis-propargyl-PEG18 has two propargyl groups at both ends. These propargyl groups reacts with azide compounds or biomolecules to form stable triazole linkages under the catalyzation of copper. The hydrophilic PEG units enhance the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro workflows
No need to immediately process samples
Nucleic acid preservation at room temperature over 2 years for DNA and 7 days for RNA
Ship stool samples at room temperature safely
Compatible with most DNA/RNA isolation methods
Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx are designed for the collection and preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Devices Dx – 50 contains 50 individual Stool Nucleic Acid Collection and Preservation Devices Dx. Each Stool Nucleic Acid Collection and Preservation Device Dx consists of Norgen’s Stool Nucleic Acid Collection and Preservation Tube Dx containing Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool Nucleic Acid Collection and Preservation Tube Dx is subsequently sent to the laboratory for DNA and/or RNA isolation and analysis. The stool DNA in preserved samples is stable for more than 2 years at room temperature, and the stool RNA in preserved samples is stable for 7 days at room temperature. DNA can be isolated from the preserved stool samples using Norgen’s Stool DNA Isolation Kit Dx (Cat. Dx27600) and RNA can be isolated from the preserved stool samples using Norgen’s Stool Total RNA Purification Kit Dx (Cat. Dx49500). These tubes are ideal for collecting and preserving DNA and RNA samples for in vitro diagnostic use for medical purposes.

[PM2510] ExcelBand™ Enhanced 3-color Regular Range Protein Marker (9-180 kDa), 250 μl x 2
Product Info
Document
Product Info
Description
The PM2510 ExcelBand™ Enhanced 3-color Regular Range Protein Marker is a ready-to-use three-color protein standard with 10 pre-stained proteins covering a wide range of molecular weights from 10 to 180 kDa in Tris-Glycine Buffer (9 to 170 kDa in Bis-Tris (MOPS) buffer and 10 to 170 kDa Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). PM2510 ExcelBand™ Enhanced 3-color Regular Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.
Features
Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.
Two reference bands — 75 kDa (red) and 25 kDa (green)
Contents
Approximately 0.2~0.6 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5), 2% SDS, 3.6 M urea, and 15% (v/v) glycerol).
Quality Control
Under suggested conditions, PM2510 ExcelBand™ Enhanced 3-color Regular Range Protein Marker resolves 10 major bands in 15% SDS-PAGE (Tris-Glycine buffer, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane.
Storage
4°C for 3 months -20°C for long term storage

endo-BCN-pentanoic acid is a click chemistry reagent containing a BCN group and a terminal carboxylic acid. The BCN group can react with azide-tagged compounds or biomolecules. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
