TCO-PEG4-DBCO is a heterobifunctional click chemistry reagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine at fast speed. DBCO is very reactive toward Azide through copper free click chemistry, the PEG spacer increases the aqueous solubility of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Genomic DNA Extraction Kit (HMW, Magnetic Beads)

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.

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.
