In 2019,Journal of Applied Laboratory Medicine included an article by Bevins, Nicholas J.; Hubbard, Jacqueline A.; Fitzgerald, Robert L.; Kelner, Michael J.. HPLC of Formula: 58-85-5. The article was titled 《A dilution method to mitigate biotin interference in cardiac troponin T testing》. The information in the text is summarized as follows:
Background: Oral biotin supplementation is known to interfere with biotin-streptavidin-based immunoassays, including Roche’s fifth-generation cardiac troponin T (cTnT) assay, which plays a critical role in the diagnosis of myocardial infarction (MI). The utility of dilution, a quick and easy method to detect and remove interferences, has not been published for biotin interference. Methods: Concentrations of cTnT were measured in pooled serum from clin. samples. Serum samples were supplemented with biotin to known concentrations, then cTnT concentrations were remeasured to assess for biotin interference. Samples were then diluted to assess for effective removal of biotin interference. Results: At cTnT values near the critical reporting range for our institution (100 ng/L) we observed significant interference in measured values with added biotin concentrations above 50 ng/mL. In specimens without added biotin, autodilution at a 1:10 ratio yielded a mean 157% capture of measured cTnT, precluding the use of autodilution for detecting and mitigating biotin interference. A 1:10 dilution with serum containing 20-30 ng/L cTnT yielded a mean capture of 107%, which was suitable for detecting underlying biotin interference in supplemented samples. Conclusions: Biotin interference, at supraphysiol. concentrations, may create an artifactual reduction in measured cTnT to levels that could lead to delayed detection of an MI. Dilution with serum of known cTnT concentration of 20-30 ng/L is a fast and effective method to mitigate the anal. consequences of biotin interference. In addition to this study using 5-((3aS,4S,6aR)-2-Oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanoic acid, there are many other studies that have used 5-((3aS,4S,6aR)-2-Oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanoic acid(cas: 58-85-5HPLC of Formula: 58-85-5) was used in this study.
5-((3aS,4S,6aR)-2-Oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanoic acid(cas: 58-85-5) may be used to elute proteins from avidin/streptavidin resins. It has been used for culturing of oligodendrocytes.HPLC of Formula: 58-85-5 And it has been used for blocking endogenous biotin during immunohistology procedures.
