permeability

[‚pər·mē·ə′bil·əd·ē]
(electromagnetism)
A factor, characteristic of a material, that is proportional to the magnetic induction produced in a material divided by the magnetic field strength; it is a tensor when these quantities are not parallel. Also known as magnetic permeability.
(fluid mechanics)
The ability of a membrane or other material to permit a substance to pass through it.
Quantitatively, the amount of substance which passes through the material under given conditions.
(geology)
The capacity of a porous rock, soil, or sediment for transmitting a fluid without damage to the structure of the medium. Also known as conductivity; perviousness.
(naval architecture)
The percentage of a given space in a ship that can be occupied by water.

Permeability

A measure of the ability of a material, such as rock or soil, to transmit fluids or air through it.

permeability

1. The property of a porous material which permits the passage of water vapor through it. Also See permeance.
2. The property of soil, rock, or mantle which permits water to flow through it.

Taking into account that achyrofuran also carries a 2,2'-biphenol moiety at the core of the molecule, we decided to explore whether achyrofuran was also able to permeabilize the cell membrane.
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.
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.
