NH-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are joined together at a secondary amine. Terminal alkynes are reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound. The secondary amine joining the two arms can be used as a nucleophile such as in alkylation via reductive amination or in forming amides with carboxylic acids or activated NHS esters. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Description 

The PM2600 ExcelBand™ 3-color High Range Protein Marker is a ready-to-use three-color protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine Buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and 10 to 235 kDa in 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). The PM2600 3-color High 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 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol). 

Quality Control 

Under suggested conditions, PM2600 ExcelBand™ 3-color High Range Protein Marker resolves 12 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

Introduction

MagPure A3 utilizes Magen’s solid-phase paramagnetic bead technology for high-throughput purification of PCR amplicons. AmPure utilizes an optimized buffer to selectively bind PCR amplicons 100bp and larger to paramagnetic beads. Excess primes, nucleotides, salts and enzymes can be removed using a simple washing procedure. The resulting purified PCR product is essentially free of contaminants.

Principle

This product is based on the purification method of high binding magnetic particles. PCR amplicons mix with MagPure A3, 100bp and larger DNA binds to magnetic beads. Excessprimes, nucleotides, salts and enzymes can be removed using a simple washing procedure and finally DNA was eluted by Elution Buffer or Water.

Advantages

• Wide application – DNA products, enzyme digestion system, PCR reaction
• High recovery – suitable for 100bp-30kb fragments
• High purity – effectively remove dNTP, primer, primer dimer, salt ion and other impurities
• Strong applicability – manual operation or automatic workstation

Storage and Stability

MagPure A3 should be stored at 2-8°C upon arrival and is stable up to 18 months under the condition. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance. Shake the reagent well before use. It should appear homogenous and consistent in color.DO NOT FREEZE.
