Web11 apr. 2024 · Summary. The spectrin-based membrane skeleton is a ubiquitous membrane-associated two-dimensional cytoskeleton underneath the lipid membrane of metazoan cells. Mutations of skeleton proteins impair the mechanical strength and functions of the membrane, leading to several different types of human diseases.

WebA selective potassium leak is observed in resealed, human red blood cell ghosts when hemolysis is performed with distilled water at pH 6.5, 0° C. The leak, which has a maximum near pH 6.7, is suppressed when either magnesium or a chelating agent is present in the hemolysing medium.

WebSince hemolysis refers to the process by which a cell becomes permeable to hemoglobin (Hb) the term “ghost” is used to describe the resultant envelope or cell-like structure (also referred to as post-hemolytic residue or stroma) that survives the transition.
