The advantage of using the tailing enzyme to introduce the Poly A tail is that it is simple and easy to implement, avoiding the instability of the plasmid caused by the introduction of too many consecutive T bases during plasmid construction.E. coli Poly (A) Polymerase does not rely on the presence of a template, and can catalyze the incorporation of ATP into the 3´ end of RNA in the form of AMP, that is, a poly A tail is added to the 3´ end of RNA. Poly (A) polymerase has a high tailing efficiency and can add 20~200 A bases to the 3´ end of RNA. Poly (A) structure helps to improve the translation efficiency of mRNA.This product is expressed in large-scale fermentation using Escherichia coli, is produced with medicinal specifications of raw materials, and strictly controls host protein residues, nucleic acid residues, etc., and conforms to GMP standard product production and quality management procedures to ensure that the production process and all raw materials can be traced.Quality requirements Project Standard Method Exterior Clear liquid Visual inspection Visible foreign body Compliance Chinese Pharmacopoeia 2020 Edition Fourth Part 1 Lamp Inspection Method (General Rule 0904) pH value 7.0-8.0 Chinese Pharmacopoeia 2020 Edition Part IV pH Determination Method (General Principle 0631) Active 4.9KUml-5.1KU/ml Tailing modification and efficiency determination method Purity ≥95% Chinese Pharmacopoeia 2020 Edition Part IV High Performance Liquid Chromatography (General Principle 0512) Endonuclease residue 004-DNA degradation does not exceed 10% Incubate SU enzyme with 004-DNA.37C for 3h Exonuclease residue 019 HindⅢ-DNA degradation does not exceed 10% Incubate SU enzyme with 019 HindⅢ-DNA at 37°C for 3h RNase residue Degradation of 293-RNA does not exceed 10% 5U enzyme and 293-RNA.

Improve the translation efficiency of RNA in eukaryotic cells.Preservation system20mM Tris-HCl; 300mM NaCl; 1mM DTT; 1mM EDTA; 0.1% TritonX-100; 50% (v/v) Glycerol, pH 7.5.ApplicationsThe intact mRNA expresses GFP protein in the cell, the capping enzyme is compared with the cap analogPrecautions1. Thermal inactivation conditions: 65°C, 20 min.2. The enzyme can only use RNA as a substrate.3. The enzyme adds AMP to the 3´ end of RNA with high selectivity, and does not add the same length of Poly (A) to all RNA molecules.4. The enzyme uses M-MuLV reverse transcriptase reaction buffer, which can also be used for reaction.5. The enzyme requires divalent cations such as Mg2+ to be active.6. The length of RNA plus A tail is affected by the amount of enzyme, ATP, reaction time and other factors. The amount of A required for different experiments will be different. The length of A can be adjusted by reducing the reaction time. The enzyme is at 37°C. About 30 A bases can be added in 30 minutes of reaction, and about 100 A bases can be added in 1 hour.7. EDTA inhibits the enzyme activity. If the reaction is stopped, it can be purified directly by adding EDTA to a final concentration of 10mM...

Stimulates AMPK phosphorylation and activation in the liver and the skeletal muscle, enhancing glucose utilization and fatty-acid combustion. Antagonizes TNF-alpha by negatively regulating its expression in various tissues such as liver and macrophages, and also by counteracting its effects. Inhibits endothelial NF-kappa-B signaling through a cAMP-dependent pathway. May play a role in cell growth, angiogenesis and tissue remodeling by binding and sequestering various growth factors with distinct binding affinities, depending on the type of complex, LMW, MMW or HMW.Post-translationalHydroxylated Lys-33 was not identified in PubMed:16497731, probably due to poor representation of the N-terminal peptide in mass fingerprinting. HMW complexes are more extensively glycosylated than smaller oligomers. Hydroxylation and glycosylation of the lysine residues within the collagene-like domain of adiponectin seem to be critically involved in regulating the formation and/or secretion of HMW complexes and consequently contribute to the insulin-sensitizing activity of adiponectin in hepatocytes. O-glycosylated. Not N-glycosylated. O-linked glycans on hydroxylysines consist of Glc-Gal disaccharides bound to the oxygen atom of post-translationally added hydroxyl groups. Sialylated to varying degrees depending on tissue. Thr-22 appears to be the major site of sialylation. Higher sialylation found in SGBS adipocytes than in HEK fibroblasts. Sialylation is not required neither for heterodimerization nor for secretion. Not sialylated on the glycosylated hydroxylysines. Desialylated forms are rapidly cleared from the circulation...

It is highly photostable and resistant to photobleaching (Shaner et al. 2004). As a result, mCherry is now the most widely used and cited red fluorescent protein. mCherry is bright although tdTomato is the brightest commercially available red fluorescent protein... Read More |
