产品描述：

Multi Nuclease all-around nuclease, also called broad-spectrum nucleic acid enzyme, is a kind of comes from Serratia Marcescens restriction endonuclease. It is capable of degradation of all forms of DNA and RNA (double-stranded, single-stranded, linear, circular or superhelical forms) under a very wide range of conditions (6Murea, 0.1M GuanidineHCl, 0.4%TritonX100, 0.1%SDS, 1mM EDTA, 1mM PMSF). The formation of 3-5 oligonucleotide residues containing 5 '-phosphate terminus is widely used to remove nucleic acids from biological products. The expression and purification of this product in Escherichia coli(E.coli) through genetic engineering can not only reduce the viscosity of cell supernatant and cell lysate in scientific research, but also improve the efficiency of protein purification and functional research. It can also be used in virus purification, vaccine production, protein and polysaccharide pharmaceutical industry as a host residual nucleic acid removal reagent, reducing the host residual nucleic acid to the peak (pg) level to improve the efficacy and safety of biological products. And can effectively prevent human peripheral blood monocyte (PBMC) clumping in cell therapy and vaccine research.

活性：25000U/mL

使用方法：

1.Sample preparation:
Adherent cells: Remove the medium, clean the cells with PBS, and remove the supernatant.
Suspension cells: Cells were collected by centrifugation, cleaned with PBS, centrifuged at 6,000rpm for 10min, and precipitates were collected.
Escherichia coli: The bacteria were collected by centrifugation, cleaned once with PBS, centrifuged at 8,000rpm for 5min, and precipitates were collected.

2.Sample treatment:
The collected cell precipitates are cleaved according to the ratio of mass (g) to volume (mL) to 1: (10-20). Cells can also be cleaved mechanically or chemically on ice or at room temperature (1g cells are about 109).

3.Enzyme addition:
the proportion of 1g cell precipitation digested by 250Units is required. You can also choose the addition plan according to the recommended dosage in the table above, increase the amount of enzyme within a certain range, and reduce the digestion time accordingly.

4.Supernatant acquisition:
The supernatant of cell lysis solution was obtained by centrifugation at 12,000rpm for 30min, and then subsequent related experiments were conducted.

储存/保存方法：

Within 1 week, 2 to 8 °C under sterile conditions after reconstitution. 12 months from date of receipt, -20 to -80 °C as supplied. Avoid repeated freeze-thaw cycles.
