DBCO-PEG4-Maleimide is PEG linker containing a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
This product provides high quality purification of total DNA from whole blood, plasma, serum, buffy coat, or other body fluids, lymphocytes and cultured cells. There is no need to use toxic phenol chloroform extraction or time-consuming alcohol precipitation. The extraction process finish in 60 minutes. Purified DNA includes genomic DNA, mitochondrial DNA, viral DNA (e.g. HBV), or DNA from other parasitic microorganisms. The obtained DNA can be directly used in PCR, viral DNA detection and other experiments.
This kit can use on manual protocol or 96 channel automated extraction system.

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.

Storage and Stability
Proteinase K, MagPure Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Norgen’s CleanAll DNA/RNA Clean-Up and Concentration Micro Kit provides a rapid method for the purification, cleanup and concentration of RNA or DNA from different isolation methods or upstream applications. The kit can be used as an alternative to organic extraction and ethanol precipitation to clean up various enzymatic reactions.
The CleanAll Kit purifies RNA from phenol/guanidine-based protocols or from various upstream enzymatic reactions such as DNase treatment, labeling and in vitro transcription. Furthermore, endotoxins can be removed from previously purified RNA solutions.
The kit can be used to clean up DNA from digestions, ligations, PCR reactions, labeling reactions, DNA modification reactions and staining. The kit also provides a protocol for the rapid removal of endotoxins from previously purified DNA down to 0.1 EU/µg DNA or less.
Purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA).
Purify all sizes of DNA, from small PCR products, native or linearized plasmids, to genomic DNA. Using an alternative protocol, even oligonucleotides and smaller DNA fragments can be purified.
