DBCO-PEG24-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.

Propargyl-PEG7-t-butyl ester comprises a propargyl group and a t-butyl protected carboxyl group. The propargyl group reacts with azide compounds via copper catalyzed Click Chemistry to form a stable triazole linkage. Under acidic conditions, the carboxyl group can be deprotected. The hydrophilic PEG units enhance solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Main Function
Extract total pathogen RNA from cell-free/low-content cell biological samples such as body fluids, serums, plasma, tissue homogenate supernatant, special design for sputum samples. Used in tuberculosis detection.
Applications
RT-PCR,PCR
Products
Pathogen RNA
Purification method
Polydisperse magnetic beads
Purification technology
Magnetic beads technology
Process method
Manual or automatic
Sample type
cell-free/low-content cell biological samples such as body fluids, serums, plasma, tissue homogenate supernatant, sputum
Sample amount
200-300μl
Adaptive instrument
Nucleic acid extractor, pipetting workstation
Principle
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. After adding magnetic particles and binding solution, DNA/RNA 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/RNA was eluted by Buffer NFW.
Advantages
Fast – several samples can be extracted in 40 minutes by column method
High quality – high purity total RNA / DNA can be directly used in various sensitive downstream applications
Safe – no phenol chloroform extraction required
Sensitive – DNA/RNA can be recovered at the level of PG
