Producing DNase I by recombinant means in an organism with much lower levels of endogenous RNase greatly facilitates purification of an enzyme with undetectable levels of RNase. The processes involved in the production and isolation of recombinant DNase I are completely devoid of animal based components which eliminates the possibility of introducing animal derived pathogens into bioprocessing procedures.Animal Free/AF. Recombinant Bovine pancreatic deoxyribonuclease 1 produced in Pichia pastoris. Chromatographically purified. Free of animal derived components, RNases & proteases.

Other family members include B7-1, B7-2, B7-H1/PD-L1, B7-H2, and PD-L2. B7 Purity:>95%, by SDS-PAGE visualized with Coomassie® Blue StainingDescription:Human B7 homolog 3 (B7-H3) is a member of the B7 family of immune proteins that provide signals for the regulation of immune responses. Other family members include B7-1, B7-2, B7-H1/PD-L1, B7-H2, and PD-L2. B7 family proteins are type I transmembrane immunoglobulin (Ig) superfamily members that contain extracellular Ig V‑like and Ig C‑like domains with a short cytoplasmic tail. Among the family members there is about 20 - 40% amino acid (aa) sequence identity. B7-H3 was initially reported to be a 316 aa type I transmembrane precursor protein that contained a signal sequence, an extracellular region with one V‑type and one C‑type Ig domain, a transmembrane segment and a short cytoplasmic tail. Subsequent studies have identified a second 110 kDa form whose precursor is 534 aa in length. Termed 4IgB7-H3 or B7-H3b, this molecule has two additional Ig-like domains (one V‑type and one C‑type) and shows a ubiquituous expression pattern. It would appear that the human 4Ig form is the principal, if not the only form of B7-H3. Its precursor contains a 26 aa signal sequence, a 435 aa extracellular region, a 31 aa transmembrane domain, and a 42 aa cytoplasmic tail. The four Ig-like domains alternate between V‑type and C‑type, and apparently are the consequence of a V‑C type tandem duplication. B7-H3b is expressed on dendritic cells as well as activated T, B and NK cells. The mouse gene differs from that of human in that it cannot code for four Ig-like domains; only a V‑type:C‑type pair. Human B7-H3b binding to an undefined receptor has shown to be inhibitory to NK cell illing and cytokine release. It also seems to be required for late stage osteoblast differentiation...

Its main physiological function is to regulate plasma pH and maintain plasma osmotic pressure.Osrhsa (recombinant human serum albumin from Oryza sativa) is a recombinant human serum albumin developed by using rice endosperm cell expression platform (oryzhiexp) and purification platform (oryzpur). It does not contain animal derived ingredients and can eliminate the risk of blood derived virus infection. Compared with fetal bovine serum (FBS), plasma derived albumin (pHSA) and bovine serum albumin (BSA), osrhsa has higher purity and better batch stability. It can be used in various research fields, including biopharmaceutical, cell therapy and cell culture of gene therapy. It can replace serum and promote cell growth. At the same time, osrhsa is also widely used in biomedical production as drug carrier, vaccine protector, cell cryoprotectant and medical device embedding agent.ApplicationBiopharmaceuticals, human vaccines, cell culture, cell storage, chemical drug molecular carriers, medical devices, in vitro diagnosis, etc.Comparison of physical and chemical properties between OsrHSA and natural human white pHSAphysicochemical propertiespHSAOsrHSAamino acid sequenceagreementN-terminal amino acidsDAHKSEVDAHKSEVC-terminal amino acidsKLVAASQAALGLKLVAASQAALGLGlycoside modificationnothingmolecular weight (MALDl)66.554 (kDa)66.550 ( a)Isoelectric point (pl)4.84.8Drug binding activityclosethermal stabilitymp 65℃mp 65℃esterase activityidenticalcrystal structureidenticalRestrictions on use:The above products are only suitable for scientific research, laboratory and production use, and cannot be directly used in human body...
