DBCO-PEG2-PFP ester

Propargyl-PEG5-NHS ester has a propargyl group and an NHS ester group. The terminal NHS ester and is an amine reactive moeity which is useful for derivatizing peptides, antibodies, amine coated surfaces etc. The propargyl group can participate in Click Chemistry reactions with azide compounds, copper is needed for catalyzation. The PEG units can enhance the hydrophilicity of the molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

Description 

The PM2610/PM2611 ExcelBand™ Enhanced 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 BisTris (MOPS) buffer and 10-235 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with different chromophores for easy identification of bands, with two reference proteins carrying enhanced intensity corresponding to a green at 25 kDa and red at 75 kDa, respectively, as separated on SDS-PAGE (Tris-Glycine buffer). The ExcelBand™ Enhanced 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 0.2~0.6 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2 % SDS, 3.6 M Urea, and 15 % (v/v) Glycerol). 

Quality Control 

Under suggested conditions, the PM2610/PM2611 Enhanced 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
