An absorbent biogenic composition includes a mixture of a base material, a plant-based oil, and a plant-based pH indicator.

The present invention relates to systems, kits, and methods for identifying subjects with increased levels of N6-trimethyl-lysine (TML) or the combination of TML and trimethylamine-n-oxide (TMAO), as well as methods of determining risk of disease (e.g., kidney disease or heart failure) based on such levels. In certain embodiments, subjects with elevated TML, or TML and TMAO are treated with a therapeutic (e.g., one that inhibits the TMA/FMO3/TMAO pathway).

The present disclosure relates to methods, compositions, and kits for concentrating and purifying one or more target analyte (s) from a bulk fluid sample. In some embodiments, the methods involve at least two first aqueous two-phase system (ATPS) compositions. Some embodiments provide a kit comprising at least two ATPS compositions, and a binding buffer. Other embodiments provide methods of treating bladder cancer in a patient in need thereof.
