Test Principle

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat HMGB-1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat HMGB-1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat HMGB-1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat HMGB-1. You can calculate the concentration of Rat HMGB-1 in the samples by comparing the OD of the samples to the standard curve.

M***aSubmitted [ Jul 06 2018 ]

Asked: Hi! I saw in the protocol of this kit that it only works with EDTA and heparin as anticoagulant. Sometimes, although protocols don\'t say it, this kits also works with citrate as anticoagulant. I would like to know whether or not this is the case. Furthermore, I would like to know how much time would it take to the shipping to arrive to Madrid (Spain). Thank you very much, Marta

Answered: Dear Marta, Thanks for your question. This kit could test with citrate plasma, but according to our experiments, the accuracy of the results decreased slightly. So we recommend to use EDTA and heparin as anticoagulant. It usually takes 3~5 days to ship the kits to arrive in Madrid (Spain). Please feel free to contact us if any question. Thanks!
