N-Boc-N-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are combined together at a Boc-protected secondary amine. Terminal alkynes are most commonly used in copper click chemistry with azides to form stable triazoles with the target molecule. The secondary amine may be deprotected under acidic conditions to allow for alkylation at that position, increasing the molecule’s structural complexity. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Principle
This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by elution buffer.
Advantages
Economy – less than 50% of the price of Qiagen and other imported products
Automatic – without labour

Storage and Stability
MagPure Particles G, MagBind Particles and Proteinase K should bestored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored dry at roomtemperature (15–25°C) and are stable for at least 18 months underthese conditions.The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

[PM2500] ExcelBand™ 3-color Regular Range Protein Marker (9-180 kDa), 250 μl x 2
Product Info
Document
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
