These substances have a great inhibitory effect on transcription. Inorganic pyrophosphatase (PPase) can hydrolyze the inorganic pyrophosphates produced in nucleic acid amplification experiments, promote Inorganic pyrophosphates are inevitably produced in the process of mRNA transcription in vitro. These substances have a great inhibitory effect on transcription. Inorganic pyrophosphatase (PPase) can hydrolyze the inorganic pyrophosphates produced in nucleic acid amplification experiments, promote the shift of reaction equilibrium to the product generation end, and increase the amount of products.The molecular weight of PPase (pyrophosphatase, inorganic, inorganic pyrophosphatase) is about 63kd, which can catalyze the hydrolysis of inorganic pyrophosphate to produce orthophosphate: P2O74_+H2O+PPase→2HPO42_. In the nucleic acid amplification experiment, PPase can hydrolyze the inorganic pyrophosphate generated with the reaction to avoid its inhibition on the reaction system. The removal of pyrophosphate can shift the reaction equilibrium to the product generation end.This product is a GMP level recombinant inorganic pyrophosphatase (yeast source) expressed by large-scale fermentation of E. coli. It is produced with raw and auxiliary materials of medicinal specifications, and the host protein residue and nucleic acid residue are strictly controlled. The product production and quality management procedures in line with GMP specifications ensure that the production process and all raw and auxiliary materials can be traced.Quality requirements project standard appearance Clear liquid Visible foreign matter Compliance with regulations PH value 7.5±8.5 activity 98U/ml-102U/ml purity ≥95% Endonuclease residues Degradation of substrate shall not exceed 10% Exonuclease residues Degradation of substrate shall not exceed 10% RNase residue Degradation of substrate shall not exceed 10% Bacterial endotoxin content ≤10EU/ml Exogenous DNA residue ≤100pg/mg Host protein residue ≤50ppm Mycoplasma detection negative Heavy metal residues ≤10ppm Follow the following specifications1.

The signal peptide is not included.FunctionCytokine that stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes.BackgroundGM-CSF is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages, and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced by endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. GM-CSF has also been reported to have a functional role on non-hematopoietic cells and can induce human endothelial cells to migrate and proliferate. Additionally, it can stimulate the proliferation of a number of tumor cell lines, including osteogenic sarcoma, carcinoma and adenocarcinoma cell lines. It is reported that GM-CSF has no biological effects across species. Recombinant Rat GM-CSF is a 14.5kDa globular protein consisting of 127 amino acid residues... Read More |
