Description 

The PM2800 ExcelBand™ 3-color Extra Range Protein Marker is a ready-to-use three-color protein standard with 13 pre-stained proteins covering an extra range of molecular weights from 10 to 310 kDa in Tris-Glycine buffer (9 to 290 kDa in Bis-Tris (MOPS) buffer and 10 to 290 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for three reference bands (one green and two red bands at 25 kDa and 75, 310 kDa respectively) when separated on SDS-PAGE in Tris-Glycine buffer. The PM2800 ExcelBand™ 3-color Extra Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for approximating the size of proteins. The marker is supplied in the gel loading buffer and is ready to use. Do NOT heat, dilute, or add reducing agents before loading.

Features

• Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.
• Three reference bands — 310 kDa (red), 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℃), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol). 

Quality Control

Under suggested conditions, PM2800 3-color Extra Range Protein Marker resolves 13 major bands in 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

Principle

The MagSelect method contains magnetic particles in an optimized binding buffer to selectively bind DNA fragments 100bp and larger to paramagnetic beads. Excessprimers, nucleotides, salts, and enzymes can be removed using a simple washing procedure. The result is a more purified PCR product.

Advantages

• High recovery – up to 80%
• High throughput – using magnetic beads purification technology

MagSelect Beads	5 ml	50 ml	500 ml

Storage and Stability

MagSelect XP 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.
