| Description | Human IgG2, Recombinant (IB2), Isotype Control, could be used for Flow Cytometry | 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 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 expression of lymphotactin is abundant in some activated T cells such as activated CD8+ T cells and other class I MHC restricted T cells. It is found in high levels in spleen, thymus, intestine and peripheral blood leukocytes, and at lower levels in lung, prostate gland and ovary. XCL1 induces its chemotactic function by binding to a chemokine receptor called XCR1.
