N-(Propargyl-PEG2)-PEG3-N-Boc is a branched PEG linker with an alkyne group and a t-butyl ester. The alkyne group reacts with azide-bearing compound in coppper catalyzed azide-alkyne Click Chemistry reaction. The Boc group can be deprotected under acidic conditions. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose.

Product Info
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

The HiPure Mini system provides a fast, simple, and cost-effective plasmid DNA miniprep method for routine molecular biology laboratory applications. HiPure Plasmid Mini Kits use silica membrane technology to eliminate the cumbersome steps associated with loose resins or slurries. Plasmid DNA purified with Mini Kits is immediately ready for use. Phenol extraction and ethanol precipitation are not required, and high quality plasmid DNA is eluted in a small volume of tris buffer or water.
Compared to other domestic products, Magen was the first to solve the stability problem of the column. Many other brands have unstable extraction concentrations, and the longer the time, the more unstable the column becomes. However, in our test of Magen kit, the quality and yield of plasmid extraction still remain stable after 5 years’ storage. For different customers, our kits can be customized. For example, Classic type is suitable for customers with low copy or unclear plasmid types. The rapid type is suitable for customers with high copy plasmids. Compared to many other brands, the plasmid DNA extracted by Magen has a longer preservation time and more thoroughly RNA removal.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method,then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – it takes only 1 minute to obtain supernatant by optimized solution (10 minutes for other brands)
High yield – up to 35µg plasmid can be binded in one column

Storage and Stability
The kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A,Buffer P1 is stable for 6 months when stored at 2-8°C.
