Propargyl-PEG4-5-nitrophenyl carbonate is heterobifunctional reagent with a propargyl group and nitrophenyl group. The propargyl group enales the formation of triazole linkage with azide compounds or biomolecules via copper catalyzed Click Chemistry. Nitrophenyl group is reactive towards the amino group of lysine by means of stable urethane linkages. The PEG units enhance the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

1. The instantaneous centrifugal function rises to the maximum speed for about 6 seconds, allowing for rapid detachment of hanging droplets from the wall;
2. Faster acceleration and deceleration rate, required to complete the experiment in a shorter time;
3. Door cover protection, overspeed and imbalance detection system, capable of real-time monitoring of the centrifugal process, ensuring the safe operation of the instrument; When the operation ends, an error occurs, or an imbalance occurs, the sound signal prompts, and the operation stops at the same time.

Product Info
Description
The PM1700 ExcelBand™ All Blue Broad Range Protein Marker is a blue protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 240 kDa in Tris-Glycine buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore, and two reference bands (at 25 kDa and 72 kDa, respectively) are enhanced in intensity when separated on SDS-PAGE (Tris-Glycine buffer).
The PM1700 ExcelBand™ All Blue Broad 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 enhanced bands — 72 kDa and 25 kDa
Contents
Approximately 0.1~0.5 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, PM1700 ExcelBand™ All Blue Broad Range Protein Marker resolves 12 major bands in SDS-PAGE (Tris-Glycine buffer, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane.
