This kit provides a simple and fast solution for the extraction of circulating nuclear acid from serum, plasma, and other cell-free liquid samples. Circulating nucleic acid refers to the free extracellular nucleic acid produced by cell apoptosis, of which fragments are generally below 1KB. The kit is based on silica gel column purification technology, which is no need for toxic phenol chloroform extraction and time-consuming alcohol precipitation during the extraction. The obtained Circulating Nucleic Acid can be directly used for quantitative PCR, liquid or solid phase chip analysis, hybridization, and SNP detection.
HiPure Circulating DNA/RNA Kit adopts a unique solution system and multiple layers of filter membranes with different pore sizes, which can efficiently process large volumes of serum and plasma samples and capture extremely small amounts of free nucleic acids.

This kit is based on silica gel column technology. Serum or other liquid samples are lysed and digested in buffer CFL. After adding buffer CFP, the protein is removed by centrifugation to obtain the supernatant. Isopropanol is added to precipitate the total nucleic acid and transferred to the column for filtration. DNA / RNA is adsorbed on the membrane of the column, while the protein is not adsorbed and removed with the filtrate.The column is washed with buffer MGW1 to remove protein and other impurities, and then washed with buffer RW2 to remove salt. Finally, DNA / RNA is eluted by low salt buffer. The eluted DNA / RNA can be directly used for quantitative PCR/ RT-PCR, liquid or solid-phase chip analysis, hybridization and SNP detection.

These kits provide everything required to isolate and purify inclusion body proteins from induced bacterial cultures. First a proprietary Cell Lysis Reagent is used to selectively lyse the cells and release inclusion bodies in their solid form. Next, inclusion bodies are dissolved and their contents released using the provided IB Solubilization Reagent. Inclusion body proteins are then further purified using spin columns for rapid and convenient buffer exchange and desalting. This kit provides a convenient way to screen recombinants prior to scaling up.
ProteoSpin™ Inclusion Body Protein Isolation Micro Kit
The process is efficient and streamlined and can process up to 12 samples in only 60 minutes. Each spin column is able to recover up to 50 µg of acidic or basic proteins. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.
ProteoSpin™ Inclusion Body Protein Isolation Maxi Kit
The procedure is efficient and streamlined and can process up to 4 samples in approximately 2 hours. Each spin column is able to recover up to 12 mg of acidic or basic proteins from 100 mL of induced bacterial culture. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.
About Inclusion Bodies
Bacteria are widely used for the expression of different proteins. However, 70-80% of the proteins expressed in bacteria by recombinant techniques are typically contained in insoluble inclusion bodies (i.e., protein aggregates). The protein of interest found in these subcellular structures is often inactive, due to incorrect folding. The production rate of recombinant proteins stored in inclusion bodies is invariably higher than those synthesized as soluble proteins. The reason behind this is thought to be the resistance of insoluble proteins to proteolysis by cellular enzymes. In addition, separation of insoluble recombinant proteins in inclusion bodies is considerably easier than that of soluble proteins. These factors have been the major influences favoring scale-up of high-value proteins using bacterial fermentation for example. Procedures for the purification of the expressed proteins from inclusion bodies are often labour-intensive, time-consuming and not cost-effective. This kit provides the essential reagents for cell disruption, inclusion body solubilization and purification using spin column chromatography – all optimized to work together thereby simplifying the process and saving a tremendous amount of time and cost.
