DBCO-PEG2-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. Please contact us for GMP-grade inquiries.

HiPure Bacterial RNA Kit uses silica gel column purification to simplify the extraction. The whole process does not require phenol chloroform extraction and time-consuming alcohol precipitation. The kit is suitable for efficiently extracting RNA from various bacterial samples. The purified RNA can be directly used for RT-PCR, Northern hybridization, etc. The kit has included lysozyme and glass beads, which can be used to treat gram-negative bacteria which is easy to be lysed, as well as gram-positive bacteria which is hard to be lysed, including enterococcus faecalis, staphylococcus, etc.

Principle
Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
Advantages
Fast – several samples can be extracted in 30 minutes
High purity – the purified RNA can be directly used in various downstream applications
High recovery – RNA can be recovered at the level of PG
Good repeatability – silica gel column purification technology can obtain ideal results every time
Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
Sufficient components – the kit contains carried lysozyme and glass beads

Storage and Stability
The kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Due to the lack of antibacterial agents, RNase Free Water may be contaminated by bacterial or fungal when placed or operated at room temperature. It is recommended to pack and store at 2-8°C to reduce contamination.
