Estimation of the potency can be made in a several ways and will be highly dependent on the nature of the target. If a purified system is used it is normal to correct for the effect of plasma protein binding (which can be measured directly in human plasma) as it is usual for the effect to be proportional to the unbound concentration [82]. This can be used to set a value for the minimum plasma concentration at steady state. 

These refinements in our knowledge of brain penetration and CNS activity of drugs feature prominently in a major medicinal review of the blood-brain barrier [14]. In vivo perfusion studies on the rate of brain uptake of several non-steroidal anti-inflammatory drugs in rats with increasing concentration of albumin in the perfusate clearly demonstrate the effect of plasma protein binding on the rate (in addition to the extent at steady-state) of brain uptake [15]. 

There have been several studies that underscore the importance of unbound concentration in cell-based studies of receptor function. In a model study of the effect of plasma protein binding on the renal transport of organic anions using the expression of various organic anion transporters (OATPs) in Xenopus oocytes, the transport of ochratoxin A, methotrexate, and estrone sulfate was found to be strongly inhibited by the addition of human serum albumin to the culture medium [16]. Similarly, the addition of oq-acid glycoprotein was found to reverse the blockade of sodium-ion current by cocaine in a preparation of cardiac myocytes [17]. 

In a previous section, the effect of plasma on PVA surface for pervaporation processes was also mentioned. In fact, plasma treatment is a surface-modification method to control the hydrophilicity-hydrophobicity balance of polymer materials in order to optimize their properties in various domains, such as adhesion, biocompatibility and membrane-separation techniques. Non-porous PVA membranes were prepared by the cast-evaporating method and covered with an allyl alcohol or acrylic acid plasma-polymerized layer the effect of plasma treatment on the increase of PVA membrane surface hydrophobicity was checked [37].The allyl alcohol plasma layer was weakly crosslinked, in contrast to the acrylic acid layer. The best results for the dehydration of ethanol were obtained using allyl alcohol treatment. The selectivity of treated membrane (H20 wt% in the pervaporate in the range 83-92 and a water selectivity, aH2o, of 250 at 25 °C) is higher than that of the non-treated one (aH2o = 19) as well as that of the acrylic acid treated membrane (aH2o = 22). 

The RUI method is a modification of the brain uptake index method [29] which was first described by Aim and Tornquist [4], The RUI approach consists of a single-arterial (e.g., intracarotid) injection technique, where the primary objective is to analyze the influx of the test substrate from the circulating blood to the retina through the BRB (i.e., blood-to-retina direction). This approach, for example, has been used to determine the retinal uptake of the test substrate which has a relatively high permeability across the BRB. The advantage of this approach is that it avoids the effect of plasma-protein binding of the test substrate and allows the retinal uptake of the test substrate...
