Purification of ovine placental lactogen (oPL) using high‐performance liquid chromatography [PDF]

open access: bronzeFEBS Letters, 1986
After initial purification of ovine placental lactogen (oPL) using the procedures described previously [(1976) Endocrinology 98, 65‐75], the oPL preparation was further purified by high‐performance liquid chromatography (HPLC) using an anionic exchange column (Bio‐Sil TSK DEAE‐2‐SW).

Genetic Changes Driving Immunosuppressive Microenvironments in Oral Premalignancy

open access: yesFrontiers in Immunology, 2022
Oral premalignant lesions (OPLs) are the precursors to oral cavity cancers, and have variable rates of progression to invasive disease. As an intermediate state, OPLs have acquired a subset of the genomic alterations while arising in an oral inflammatory
