In the course of the LER phenomenon, a common formulation matrix containing sodium citrate and polysorbate in biopharmaceuticals ends in The shortcoming to Get better LPS inside a time-dependent manner when spiked into undiluted samples [19,twenty]. It's not at all totally clear whether or pyrogen test for injections not masked endotoxins are biologically Lively in vivo, While masked endotoxin is claimed for being a strong set off of immune responses [21]. It's appealing to note that an analogous phenomenon in clinical specimens is assumed to arise during disaggregated LPS–HDL binding, for instance [22].
