Most of the ER, vacuolar membranes and plasma membrane are found in the heavy membrane fraction, whereas the light membrane fraction is enriched in Golgi membranes [24].
The presence of SAPO-34 in PVDF membrane enriched membrane porosity and affinity towards CO2.
Like invadopodium, the F-actin-enriched structures found in p185wt cells are associated with the membrane and enriched with multiple structural/regulatory proteins involved in the regulation of actin cytoskeleton assembly, cell adhesion and extracellular matrix degradation (40, 41).
M, membrane enriched; C, cytosolic enriched; P, insoluble cytoskeletal enriched; N, nuclear enriched; CB, chromatin bound fraction.
Rafts are membrane regions enriched in sphingolipids and cholesterol: this composition makes raft structures less fluid than the surrounding phospholipids bilayer, and for this reason, they are involved in cell shaping, cytoskeleton anchoring to the plasma membrane, trafficking of proteins and receptors clustering or regulation.
Other transcripts may be associated with our nuclear fractions because they are enriched in a part of the ER or other membrane structure connected to the nucleus.
The crude membrane fractions were enriched for authentic membrane proteins.
A membrane fraction enriched in plasma membrane vesicles was prepared as described by Briskin et al. (1987) with minor changes.
In a healthy Schwann cell, the cell membrane is enriched in plasmalogens.
The homogenates were centrifuged, the supernatants were spun, and the resulting pellets, containing membrane fractions enriched with plasma membranes and intracellular vesicles, were suspended in the isolation solution.
