(pĕr'mē-ă-bil'i-tē)
The property of being permeable.

permeability

passage of substances through a membrane
  • increased vascular permeability capillary state in acute inflammation; larger gaps appear between tunica intima cells, permitting passage of large molecules (e.g. plasma proteins) and cells (e.g. neutrophils, macrophages, fibroblasts, platelets and sometimes erythrocytes) from the capillary into the tissue spaces

  • vascular permeability passage of small molecules (e.g. water, oxygen, carbon dioxide and glucose) into and out of the capillary; normal state, permitting tissue respiration

per·me·a·bil·i·ty

(pĕr'mē-ă-bil'i-tē)
The property of being penetrable.

permeability (pur´mēəbil´itē),

n the degree to which one substance allows another substance to pass through it.

permeability

EPT involves the use of extremely brief, intense, pulsed electric fields to temporarily permeabilize cell membranes, creating transient pores, which allow the entry of anti-cancer drugs directly into the cancer cell where the drug is more effective.
During ICSI process the effects of sperm membrane disruption to permeabilize to exogenous DNA and electrical activation of oocytes on in vitro development and transgenesis in preimplantation ICSI embryos were tested.
Electroporation involves the use of extremely brief, intense, pulsed electric fields to temporarily permeabilize cell membranes, creating transient pores, which allow the entry of various types of molecules such as DNA and proteins into the cell.
a) * Culture cells with antigen-specific or nonspecific (PMA(b)/ionomycin,CD3/CD28) stimuli * After an appropriate stimulation period, culture cells with an inhibitor of Golgi transport (secretion) to retain newly synthesized cytokines in the cell * Stain for surface markers * Fix and permeabilize cells * Stain for intracellular cytokines (a) Very important: for accurately counting cells that are producing cytokines, it is crucial to eliminate cells that died before the staining steps are initiated.
