Precipitation of serum proteins by polyethylene glycol (PEG) in pretransfusion testing [PDF]

Immunohematology, 1999
Abstract Polyethylene glycol (PEG) is used as a potentiator of blood group antigen-antibody interactions. Although PEG is known to precipitate immunoglobulins, we could find no reports of this reagent entrapping red blood cells (RBCs) in irreversible clumps.

Assessment of macroprolactinemia by the polyethylene glycol precipitation method

Medicinski pregled, 2020
Introduction. Macroprolactinemia is one of the common causes of hyperprolactinemia, especially in cases where standard routine commercial immunometric assays are used for prolactin level measurement. Two forms of prolactin, inactive dimeric prolactin (50 - 60 kDa) and a low-activity tetramer (molecular weight above 150 kDa), contribute to ...

Size fractionation of double-stranded DNA by precipitation with polyethylene glycol [PDF]

Nucleic Acids Research, 1975
We show that DNA molecules of differing molecular mass are separable by selective precipitation with polyethylene glycol (PEG+.. Higher molecular mass DNA precipitates at lower PEG concentrations than lower molecular mass DNA. Double-stranded DNA can be fractionated at least in the range of 3 times 10-7 to 1 times 10-5 daltons.

Macroprolactinemia Associated with Anti-Prolactin Antibodies: A Case Report

Endocrinology Research and Practice, 2022
Macromolecular form of prolactin is generally associated with asymptomatic hyperprolactinemia. Increases in molecular size may result from self-aggregation or binding with antiprolactin antibodies.

Detection of Macro-Aspartate Aminotransferase (AST) in an Asymptomatic Patient with Persistent Elevation of AST

Korean Journal of Clinical Laboratory Science, 2021
The persistent increase of aspartate aminotransferase (AST) due to the presence of a macro-AST can confuse diagnostic or therapeutic decisions in many clinical situations. In this study, we report a case of isolated and persistent AST-elevation without
