Total Thiol Assay - Cell Biolabs
WebThe assay, performed at room temperature, can be completed in 5 min. As low as 2 - 10 uM free thiols can be detected, including low-molecular weight thiols and those thiol groups on proteins. Each kit provides sufficient material for 250 assays, and includes a cell/tissue extraction solution for preparation of crude lysates for the assay. The ... Web2. Thiol Quantification Kit. The thiol quantification assay kit allows you to quantify the amount of thiol/sulfhydryl (-SH) groups in samples of thiolated proteins or antibodies. Quantifying the number of free thiols in a sample can be useful in a number of applications and allows for a more controlled conjugation reaction. WebThe Fluorometric Thiol Quantitation Kit provides an ultrasensitive assay to quantitate the thiol content of small molecules. The proprietary thiol sensor generates a strongly fluorescent adduct (λex = 490/λem = 520 nm) upon reacting with a thiol-containing compound. In addition, both absorption and emission spectra of the thiol adduct are pH ... bulk rijst kopen
