The active center of its gene Is it sterile: YesMetallozyme is a water-soluble protein using recombinant genes, lyophilized and irradiated with cobalt-60, and aseptic packaging of celine bottles. A recombinant gene protein constructed according to the chemical structure of cephalosporins and penan. The active center of its gene fragment can destroy the chemical structural formula of cephalosporins and penan antibiotics, so that the antibacterial properties of the two drugs are lost after ring opening/chain breaking.When doing sterility check of antibiotics, use a manual syringe to absorb sterile water and inject it into the drug vial, shake well, dissolve, and then suck it out. Add to 500ml solution of 0.9% sodium chloride, shake well, do not dissolve with the needle on the incubator, input, avoid high concentration of solution through the filter membrane, resulting in difficult to rinse thoroughly.Here, it is emphasized again: when doing sterile examination of antibiotics, it is necessary to inject sterile water into the manual syringe to dissolve the sample, and then transfer the dissolved sample to 500ml solution of 0.9% sodium chloride, so that the sample will not cause local concentration too high, difficult to wash thoroughly through the filter membrane.During sterility test, take 1 bottle of freeze-dried metal enzyme powder and add 5ml of sterile water to dissolve, shake well to make a metal enzyme solution, take 2ml of enzyme solution and put 1500ml of washing solution and shake well. After the rinse solution has washed the filter membrane of the incubator, the pump is exhausted. A manual syringe was used to Pierce the respiratory mouth of the three incubators, and 1ml of enzyme solution was added to each of them, and the enzymes were spread on the entire surface of the filter membrane as far as possible. Then, the high concentration of enzymes was fully in contact with the filter membrane of the incubator, so as to destroy (neutralize and inactivate) the residual cephalosporins and penem drugs on the filter membrane, and then pumped into the corresponding medium and shook well. Positive pairs were treated with 1ml of E. coli (100CFU/ml).Adding 1ml of the metal enzyme solution to the three incubators can remove the residual cephalosporins and penem on the inner wall of the incubators and the surface of the filter membrane.Shake the positive pair gently once a day in the morning and afternoon.Customers can do methodological verification according to the above, but also according to the actual operation of the verification...

Purity:>98%, by SDS-PAGE visualized with Coomassie® Blue Staining.Description：Heme oxygenase (HMOX) is the rate limiting enzyme in heme catabolism. It cleaves heme to biliverdin, carbon monoxide, and iron. The biliverdin is subsequently converted to bilirubin by biliverdin reductase. The mechanism of HMOX is unique in that heme serves as the substrate of the enzyme and as the prosthetic group for the activation of iron-bound O2. HMOX activity is highest in spleen where senescent erythrocytes are sequestered and destroyed. Two isoforms, HMOX1 and HMOX2, are expressed in most tissues. HMOX1 is an inducible enzyme in response to heme, heavy metals, oxidative stress, cytokines, and many drugs. Whereas HMOX2 displays a constitutive expression. HMOX1 is expressed mainly in spleen, liver, and kidney, and HMOX2 is prominently expressed in the brain and testes. The increased expression of HMOX1 levels is related to a variety of pathological states, where it functions as a cytoprotective molecule through its by products. HMOX1 also plays important roles in the regulation of cell proliferation, differentiation, and apoptosis...

KGF expression is restricted to cells of mesenchymal origin. When secreted, it acts as a paracrine growth factor for nearby epithelial cells (1). KGF speeds wound healing by being dramatically upregulated in response to damage to skin or internal structures that results in high local concentrations of inflammatory mediators such as IL-1 and TNF-alpha. (2, 5). KGF promotes cell migration and invasion, and mediates melanocyte transfer to keratinocytes upon UVB radiation (6, 7). It has been used ectopically to avoid chemotherapy-induced oral mucositis in patients with hematological malignancies (1). Deletion of KGF affects kidney development, producing abnormally small ureteric buds and fewer nephrons (8). It also impedes hair follicle differentiation (9). The 194 amino acid (aa) KGF precursor contains a 31 aa signal sequence and, like all other FGFs, an ~120 aa beta -trefoil scaffold that includes receptor- and heparin-binding sites. KGF signals only through the IIIb splice form of the tyrosine kinase receptor, FGF R2 (FGF R2-IIIb/KGF R) (10). Receptor dimerization requires an octameric or larger heparin or heparin sulfate proteoglycan (11). FGF-10, also called KGF2, shares 51% aa identity and similar function to KGF, but shows more limited expression than KGF and uses an additional receptor, FGF R2-IIIc (12). Following receptor engagement, KGF is typically degraded, while FGF-10 is recycled (12). Mature human KGF, which is active across species, shares 98% aa sequence identity with bovine, equine, ovine and canine, 96% with mouse and porcine, and 92% with rat KGF, respectively... Read More |
