UltraNuclease ELISA Kit - 36701ES
UltraNuclease, also known as a non-restrictive endonuclease, broad-spectrum nuclease, is a non-specific endonuclease derived from Serratia Marcescen, which hydrolyzes internal phosphodiester bonds between any nucleotides in nucleic acids to produce 5'-monophosphate oligonucleotides of 2-5 bases in length. It can degrade DNA and RNA in various forms (double-stranded, single-stranded, linear, circular, native or denatured) under a very 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) and is widely used to remove nucleic acids from biological products. UltraNuclease can also be removed by corresponding methods subsequently.
This kit uses the principle of double-antibody sandwich enzyme-linked immunosorbent assay (sandwich ELISA) to detect the residues of denatured and non-denatured UltraNuclease. First, coat the microplate with an anti-UltraNuclease rabbit polyclonal antibody to form a solid-phase antibody. Second, add UltraNuclease standard and test sample to the solid-phase antibody microplate, then add biotin labeled Anti-UltraNuclease polyclonal antibody, and finally, add horseradish peroxidase-labeled streptavidin (SA-HRP) to form an antibody + antigen + antibody-Biotin + SA-HRP complex. Subsequently, TMB substrate was added to the complex to observe color reaction after washing the complex. TMB is converted into blue under the catalysis of HRP enzyme and finally converted into yellow in the presence of acid, and the shade of color is positively correlated with the amount of UltraNuclease in the sample.
The detection quantification range of this kit is 0.047-3 ng/mL; the lower detection limit is 23.5 pg/mL. Manual Packaging size: 96 T

Double-stranded RNA (dsRNA) ELISA kit - 36717ES
Double-stranded RNA (dsRNA) emerges as a by-product during the in vitro transcription of mRNA. This by-product possesses immunogenic properties within the human body, capable of provoking an immune response, consequently diminishing mRNA levels. This renders dsRNA a troublesome process impurity necessitating thorough elimination and stringent control of its residual presence.
To address this concern, the Double-stranded RNA (dsRNA) ELISA detection kit employs the experimental principles of a double-antibody sandwich enzyme-linked immunoassay (ELISA) for the quantification of residual dsRNA. The Kit can not only be used in the detection of regular dsRNAs, but also in detection of peudo UTP, N1-Me-peudo UTP and 5-OMe-UTP modified dsRNAs.
The procedure involves adding both a standard and the test sample onto an enzyme plate (designated as 36717-A) previously coated with anti-dsRNA antibodies. Subsequently, biotin-labeled dsRNA detection antibodies (36717-F) are added in a diluted form. Finally, Streptavidin-HRP (SA-HRP) (36717-G) is introduced to create a complex comprising antibodies, antigens, biotin, and SA-HRP.
Following plate washing, the addition of TMB chromogenic solution (36717-K) initiates color development. Under the influence of HRP enzyme catalysis, TMB undergoes a transformation from colorless to blue, which is then halted through the application of the stop solution (36717-L). Ultimately, this transformation results in a yellow hue, the intensity of which correlates positively with the quantity of dsRNA identified in the sample.
This kit serves a versatile purpose, enabling optimization of the biological product purification process, impurity control during intermediate stages, and release testing for final product assessment. Manual Packaging size: 48 T / 96 T
