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. A liquid preparation in 5mM Calcium Acetate, 4mg/ml glycine, pH 5.0 and 50% glycerol. Supplied with 10x reaction buffer.Storage Buffer : 5mM calcium acetate, 4mg/ml glycine, pH 5.0 and 50% glycerol.DNase I Reaction Buffer (10X): 500mM Tris-HCl, 10mM MgSO4, 1mM CaCl2, pH 7.8, provided.application：Recombinant DNase I is suitable for such applications as:• Removing genomic DNA from RNA preparations prior to RT-PCR• Degradation of DNA templates after transcription reactions• Removing unwanted DNA from samples prior to Northern blotting• Removing DNA during biopharma and bioprocessing procedures...

Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0.1-0.5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA.ApplicationUseful for the proteolytic inactivation of nucleases during the isolation of DNA and RNA.Removes endotoxins that bind to cationic proteins such as lysozyme and ribonuclease A.Reported useful for the isolation of hepatic, yeast, and mung bean mitochondriaDetermination of enzyme localization on membranesTreatment of paraffin embedded tissue sections to expose antigen binding sites for antibody labeling.Digestion of proteins from brain tissue samples for prions in Transmissible Spongiform Encephalopathies (TSE) research...

(1989) from the culture supernatant of embryonic lung fibroblasts, which is a member of the FGF family, namely FGF-7. KGF is an effective epithelial-specific growth factor secreted by mesenchymal cells and distributed in epithelial cells. Its mitotic activity is mainly manifested in keratinocytes, which can specifically promote the proliferation, migration and differentiation of epithelial cells. It is closely related to organ development, wound repair, tumor genesis and immune reconstruction.Activity definition: The ED50 value is less than 1.0 ng/ml, that is, the corresponding activity unit is greater than or equal to 1 x 10*6 units/mg, as determined by the proliferation method of cultured MCF-7 cells...

The PEDF is a Purity＞97% by SDS-PAGE and HPLC analyses.FunctionPigment epithelium-derived factor (PEDF) is encoded by the SERPINF1 gene in humans and found in verebrates. It is a secreted phosphoglycoprotein that belongs to the clade F subfamily, serpin superfamily of proteinase inhibitors. The PEDF is a noninhibitory serpin with neurotrophic, anti-angiogenic, and anti-tumorigenic properties. It is synthesized as a 418 a.a. about 50kDa precursor that contains a 19 a.a. signal sequence and a 399 a.a. mature region that shows a pyroglutamate at Gln20. Like other serpins, it contains three β-sheets, 810 α-helices, and a C-terminal RCL (reactive center loop). Unlike other serpins with Ser protease inhibiting activity. PEDF has functions of inducing extensive neuronal differentiation in retinoblastoma cells, inhibiting of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. PEDF is researched as a therapeutic candidate for treatment of such conditions as choroidal neovascularization, heart disease, and cancer... Read More |
