This product is a 2× Mix pre-mixed reagent that enables up to four fluorescent quantitative PCR reactions in a single reaction well. This product contains the genetically modified antibody method to hot-start Taq enzyme, greatly improving the amplification sensitivity and specificity. At the same time, this product has deeply optimized the multi-reaction buffer, which can improve the amplification efficiency of the reaction and promote the effective amplification of low-concentration templates. This product can be used for genotyping and multiplex quantitative analysis.
This product is a bacteriophage T7 RNA polymerase derived from recombinant protein expression in Escherichia coli. It catalyzes the 5'→3' synthesis of RNA on double-stranded DNA from its T7 promoter sequence (5'-TAATACGACTCACTATAG*-3') and uses NTPs as substrates. The DNA with double-stranded linear blunt ends or 5'protruding ends can be used as templates for T7 RNA polymerase, so linearized plasmids and PCR products can be used as templates for in vitro synthesis of RNA.
UltraNuclease, also known as non-restrictive endonuclease and broad-spectrum nuclease, is a nonspecific endonuclease recombinant from Serratia Marcescen and expressed in Escherichia coli (E. coli). It can cleave between any nucleotides in the chain, completely digest nucleic acids into 5'-monophosphate oligonucleotides of 2-5 bases in length, and can degrade various forms of DNA and RNA (double-stranded, single-stranded, linear, circular, native or denatured) DNA and RNA under a broad range of conditions (6 M Urea,0.1 M Guanidine HCl, 0.4% Triton X-100, 0.1% SDS, 1 mM EDTA, 1 mM PMSF), which is widely used to remove nucleic acids from biological products. The product is expressed and purified in Escherichia coli (E. coli) by genetic engineered, and prepared under the GMP environments. It can reduce viscosity of cell supernatant and cell lysate in scientific research, to increase protein purification efficiency and enhance protein functional research. The product can also reduce host nucleic acid residues to pg-grade, improving the performance and safety of biology products of applications including virus purification, vaccine manufacturing, and protein/polysaccharide pharmaceutical manufacturing. Besides, the product can also be applied to prevent clumping of human peripheral blood mononuclear cells (PBMC) in cell therapy and vaccine development.
You can find development history, characteristics, advantages and other important info of DSS UC Modeling in the article.
Since its establishment, it has developed, produced and sold thousands of molecules, proteins and cells related biological reagents, which can meet the integrated and specific procurement needs of customers. Relying on the technical advantages of protein transformation and enzyme evolution and the rich experience in the biological reagent industry, Yeasen has built comprehensive product lines of various high quality products.
