DBCO-PEG9-DBCO is a click chemistry linker with two DBCO groups and a hydrophilic PEG spacer arm. DBCO is reactive with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. The hydrophilic PEG9 arm increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
The FluoroStain™ DNA Fluorescent Staining Dye is designed to be a safer replacement for conventional Ethidium bromide (EtBr) which poses a significant health and safety hazard for its users. The FluoroStain™ DNA Fluorescent Staining Dye offers at least 10 times sensitivity in DNA detection levels, and is capable of detecting double stranded DNA (dsDNA) fragments up to 0.04 ng in electrophoresis analysis. The FluoroStain™ DNA Fluorescent Staining Dye shows a high specificity to the dsDNA, with negligible background signal, making the destaining process entirely optional. FluoroStain™ DNA Fluorescent Staining Dye is compatible with both the conventional ultra violet gel-illuminating systems as well as the less harmful long wave length blue light illumination systems. The emission when bound to dsDNA is 522 nm, while its excitation peaks are at 270, 370 and 497 nm.

The Genomic DNA Extraction Kit (HMW, Magnetic Beads) provides a reliable and fast process for extracting high molecular weight (HMW) genomic DNA from cells, blood, and tissues using Solid Phase Reversible Immobilization (SPRI) magnetic beads. With our proprietary magnetic beads technology, the kit eliminates the tedious centrifuge steps for columns. The kit provides a reliable and simple approach for high-quality genomic DNA isolation with fast magnetic response time and high binding capacity.

Cat.# 50016 Genomic DNA Extraction Kit for Tissues (HMW, Magnetic Beads)
The extracted HMW genomic DNA size ranges are dependent on the beads resuspension: 50-150 kb by tube tapping and 40-100 kb by tube vortexing. Purified DNA is recovered at high yield and high purity without RNA contamination. The typical purity ratios of A260/A280 are around 1.8-2.0, and A260/A230 are around 2.2-2.5. Purified HMW genomic DNA is suitable for applications such as long-read sequencing, linked-read genome assembly, long range PCR, optical mapping, and other general applications.
Features
A portion of the extracted genomic DNA samples were loaded on a PFGE gel with a DNA ladder indicated. Sample A: liver tissue; Sample B: intestine tissue; Sample C: whole blood; Sample D: cultured 293T cells.
Cultured Cell samples
Cultured cells are collected and are resuspended in a buffer and then lysed with a lysis buffer, then mixed with beads to bind genomic DNA. The samples are mixed with a buffer and after washing steps, genomic DNA is eluted in the Elution Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities.
Blood samples
Whole blood is resuspended in the RBC buffer to remove RBC. The remaining leucocytes are lysed with a lysis buffer, then mixed with beads to bind genomic DNA. The samples are mixed with a buffer and after washing steps, genomic DNA is eluted in Elution Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities.
Tissue samples
Tissues are homogenized and lysed, then mixed with beads to bind genomic DNA. The samples are mixed with a buffer and after washing steps, genomic DNA is eluted in Elution Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities.
