DBCO-PEG1-NHS Ester is a PEG containing molecule containing an NHS ester moiety that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description 

The PM1600 ExcelBand™ All Blue Regular Range Plus Protein Marker is a blue protein standard with 11 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 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 PM1600 ExcelBand™ All Blue Regular Range Plus 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, PM1600 ExcelBand™ All Blue Regular Range Plus Protein Marker resolves 11 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

Introduction

This product is suitable for rapid extraction of RNA (include miRNA) from tissue, cells, blood, s and other clinical samples. RNA can be used directly for RT-PCR, quantitative RT-PCR, test of virus DNA and so on.

Principle

This product is based on silica column purification. Remove paraffin by Buffer DPS. Sample lysis withproteinase K digestion requires only 15 minutes. After lysis, samples are incubated at 80ºC for 15 minutes. Transfer to an adsorption column and RNA is adsorbed on the membrane, while protein is not adsorbed andis removed with filtration. After washing proteins and other impurities, RNA was finally eluted with low-saltbuffer.

Advantages

• Efficient DNA removal – one step RNA extraction can effectively remove genomic DNA
• High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
• Fast – the whole extraction only takes 15-25 minutes
• Nontoxic – no toxic phenol chloroform extraction is required in the extraction

Storage and Stability

Proteinase K should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.
