DBCO-PEG12-DBCO is a monodisperse click chemistry linker containing two terminal DBCO groups with hydrophilic PEG spacer arm. DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
The DM5100 ExcelBand™ Super Range DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA Ladder DM5100 is composed of 26 individual DNA fragments: 25k, 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1.2k, 1k, 900, 800, 700, 600, 500, 450, 400, 350, 300, 250, 200, 150, 100 and 50 base pairs derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains four enhanced bands (3k, 1.2k, 500 and 200 bp) for easier reference. In addition, three tracking dyes, Xylene cyanol FF, Bromophenol blue and Orange G which mimic the migration of 4,000 bp, 500 bp and 50 bp dsDNA during electrophoresis are added for real time monitoring.

Annexin A1 (ANXA1) is a membrane protein that plays a role in innate and adaptive immunity by controlling the biosynthesis of inflammation, prostaglandins, and leukotriene mediators. This target is overexpressed in 97% of all samples from patients with with hairy cell leukemia, and is absent in other B-cell lymphomas. High ANXA1 expression is frequently associated with advanced stage esophageal and esophagogastric junction adenocarcinoma, and is also linked to advanced and metastatic disease states.
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.

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.

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.
