Aug 01, 2019 · The majority of acidic drugs have low steady-state distribution volumes (V ss) in the range of 0.1–0.3 l/kg (Grime et al., 2013) due to a combination of high plasma protein binding (PPB) and low tissue distribution (Smith et al., 2010) unless active hepatic uptake is a determining factor (Grover and Benet, 2009; Gardiner and Paine, 2011).
Aijiren vials and caps provide simple ways to boost laboratory productivity and return on investment. Aijiren premium certified vials, caps, high recovery vials, and vial inserts offer industry-leading performance; from the lowest bleed septum materials in our caps to the most inert glass vial materials, we are continuously refining our offerings by addressing small details delivering
efficiently partitioned from the water sample into a modified PSDB SPE sorbent (Varian’s PPL) and is sufficiently volatile and thermally stable for gas chromatography. Extraction is performed by passing a 1L water sample through a SPE cartridge with 500mg modified PSDB (PPL). The phenols are eluted with methylene chloride.
Apr 25, 2003 · Plasma protein binding. NLCQ-1 protein binding to human and mouse plasma proteins over the range 100–400 ng/ml of drug was 99% and 70%, respectively. High protein binding was observed when NLCQ-1 protein binding was further evaluated in dilute (1:10) human plasma, α 1-acid glycoprotein and human serum albumin (Table 1).

Silanized Chromatography Vials. Because the surface of laboratory glassware is slightly acidic, it can adsorb some analytes — particularly amines. In low level analyses, such losses can be significant. To prevent sample loss through adsorption, glassware used in low level analyses usually is silanized.

protein binding to be limited as isoniazid, pyrazinamide and ethambutol are very polar compounds. If protein binding proves to be low, ultrafiltration as a means of deproteinization of the serum samples can be applied. Although ultrafiltration is commonly used for determin-ing free unbound drug levels in serum [21], it has pre-viously been
Jun 01, 2007 · Amphetamine-related compounds are weak bases with low protein binding facilitating the transfer of lipid-soluble compounds from blood to other fluids and/or tissues. This can lead to an accumulation in biological samples with pH values lower than that of plasma (pH 7.4) or ion trapping of the drugs in the more acidic matrix [ 8 , 16 , 22 , 23 ].
