In the LER phenomenon, website a typical formulation matrix that contains sodium citrate and polysorbate in biopharmaceuticals brings about The lack to Get well LPS inside of a time-dependent method when spiked into undiluted samples [19,20]. It is not totally distinct whether or not masked endotoxins are biologically Energetic in vivo, Whilst masked endotoxin is documented to generally be a potent cause of immune responses [21]. It is actually intriguing to note that the same phenomenon in scientific specimens is assumed to occur in the course of disaggregated LPS–HDL binding, For illustration [22].
