Human Ribonuclease pancreatic (RNASE1/RIB1/RNS1) ELISA Kit

Pancreatic ribonucleases (EC 3.1.27.5, RNase, RNase I, RNase A, pancreatic RNase, ribonuclease I, endoribonuclease I, ribonucleic phosphatase, alkaline ribonuclease, ribonuclease, gene S glycoproteins, Ceratitis capitata alkaline ribonuclease, SLSG glycoproteins, gene S locus-specific glycoproteins, S-genotype-assocd. glycoproteins, ribonucleate 3'-pyrimidino-oligonucleotidohydrolase) are pyrimidine-specific endonucleases found in high quantity in the pancreas of certain mammals and of some reptiles. Specifically, the enzymes are involved in endonucleolytic cleavage of 3'-phosphomononucleotides and 3'-phosphooligonucleotides ending in C-P or U-P with 2',3'-cyclic phosphate intermediates. Ribonuclease can unwind the RNA helix by complexing with single-stranded RNA; the complex arises by an extended multi-site cation-anion interaction between lysine and arginine residues of the enzyme and phosphate groups of the nucleotides

Human Ribonuclease pancreatic (RNASE1/RIB1/RNS1) ELISA Kit has high sensitivity and excellent specificity for detection of Human RNASE1. No significant cross-reactivity or interference between Human RNASE1 and analogues was observed.

This Human Ribonuclease pancreatic (RNASE1/RIB1/RNS1) ELISA Kit employs a two-site sandwich ELISA to quantitate RNASE1 in samples. An antibody specific for RNASE1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyRNASE1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for RNASE1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of RNASE1 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
