Propargyl-PEG4-acid is a PEG reagent with an alkyne and a terminal carboxylic acid. The carboxylic acid reacts with primary amine groups with the help of activators (e.g. EDC, or HATU). The 4-unit PEG spacer increases hydrophilicity. The alkyne can participate in copper-catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
SMOBIO’s B-BOX™ is a long wavelength, blue light LED epi-illuminator. It is compact in design and robust in structure. The B-BOX™ epi-illuminator provides an unprecedented level of safety for its user due to its non-UV light source and a low operating voltage of only 12 Volts, as well as its capability working with non-carcinogenic DNA/ protein dye. The B-BOX™ comes with high quality non-flickering LED light that is highly sensitive for DNA and protein dye. B-BOX™ can greatly ease the routine chore of gel extraction, enabling easy visualization and gel cutting even in bright ambient light. The multi-angle filter plate (Cat. No. VE0102) provides optimal angles for gel cutting, visualization, and documentation. The B-BOX™ also comes with amber colored filter goggles (Cat. No. VE0103) for gel cutting and visualization. The Phox™ Photobox (Cat. No. VE0104) provides a mini darkroom environment for images taken with any smartphone. Finally, a built-in barrier system around the working area helps facilitate cleaning.
Features
Improved cloning efficiency
Compact, lightweight, and portable (less than 1 kg in weight)
Safety features include : 470 nm long wavelength, without any UV radiation hazard to its user
Compatible with non-carcinogenic, non-ethidium bromide DNA staining dye
User friendly: Samples are easy to visualize (when using the filter plate or goggles)
LED light source lasts up to 50,000 hours
Superior detection sensitivity: ≤ 0.04 ng of DNA when using FluoroStain™ DNA Fluorescent Staining Dye, ≤3 ng of protein when using FluoroStain™ Protein Fluorescent Staining Dye (as sensitive as silver stain)
Adjustable and removable filter plate allows for gel cutting, visualization, and documentation
Built-in barrier design, for easy clean up
Visible in bright ambient light
Emphasizes minimal power reliance, low heat generation, with its own built-in heat sink

Norgen’s EXTRAClean Urine Cell-Free Circulating RNA Purification Kits provide a fast, reliable, reproducible, and simple procedure for isolating circulating RNA and exosomal RNA from various urine inputs ranging from 250 μL and up to 30 mL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real-time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extensions, and expression array assays.
EXTRAClean Cell-Free Circulating RNA Purification Mini Kit: For sample volumes ranging from 250 μL to 2 mL
EXTRAClean Cell-Free Circulating RNA Purification Midi Kit: For sample volumes ranging from 2mL to 10mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL
EXTRAClean Cell-Free Circulating RNA Purification Maxi Kit: For sample volumes ranging from 10 mL to 30 mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.
All sizes, including miRNA and small RNA (< 200 nt)
