endo-BCN-PEG2-NHS ester is aclick chemistry crosslinker containing an NHS ester group. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group is reactive with azide-tagged biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-C5-acid is an analog of DBCO-Acid with an extended 5-carbon atom spacer arm. The extended 6-carbon atom spacer arm improves its derivatization efficiency and the stability of the yielded conjugates. This spacer arm also improves solubility in organic solvents such as dichloromethane, chloroform, THF, and ethyl acetate. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

Product Info
Description
The PM2500 ExcelBand™ 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). PM2500 ExcelBand™ 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 0.1~0.4 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, PM2500 ExcelBand™ 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
