Abstract
Protein G can be a valuable binding agent for antibodies and immunoglobulins in methods such as immunosensors, chromatographic-based immunoassays, and immunoaffinity chromatography. This report used the method of peak decay analysis along with frontal analysis and zonal elution studies to characterize the binding, elution and regeneration properties of affinity microcolumns that contained immobilized protein G. Frontal analysis was employed with rabbit immunoglobulin G (IgG) to characterize the binding capacity of these affinity microcolumns. Zonal elution experiments looking at the retained peaks for small injections of labeled rabbit IgG were used to optimize the column regeneration conditions. Peak decay analysis was then used to look at the effects of flow rate and elution pH on the release of several types of IgG from the protein G microcolumns. This approach made it possible to obtain detailed information on the use and behavior of such columns, as could be used in future work to optimize the capture or analysis of IgG and antibodies by such devices. The same approach and tools that were used in this report could also be adapted for work with affinity columns that make use of other supports, binding agents or targets.

Abstract
The last few decades have witnessed the development of many high-performance separation methods that use biologically related binding agents. The combination of HPLC with these binding agents results in a technique known as high performance affinity chromatography (HPAC). This review will discuss the general principles of HPAC and related techniques, with an emphasis on their use for the analysis of biological compounds and pharmaceutical agents. Various types of binding agents for these methods will be considered, including antibodies, immunoglobulin-binding proteins, aptamers, enzymes, lectins, transport proteins, lipids, and carbohydrates. Formats that will be discussed for these methods range from the direct detection of an analyte to indirect detection based on chromatographic immunoassays, as well as schemes based on analyte extraction or depletion, post-column detection, and multi-column systems. The use of biological agents in HPLC for chiral separations will also be considered, along with the use of HPAC as a tool to screen or study biological interactions. Various examples will be presented to illustrate these approaches and their applications in fields such as biochemistry, clinical chemistry, and pharmaceutical research.

Abstract
An immunoaffinity chromatographic method was developed using an antibody mediated immunosorbent to selectively extract and purify 10 quinolones (marbofloxacin, norfloxacin, ciprofloxacin, lomefloxacin, danofloxacin, enrofloxacin, difloxacin, sarafloxacin, oxolinic acid, and flumequine) in chicken muscle followed by HPLC. The operating conditions of the immunoaffinity chromatography (IAC) column were optimized, and the IAC has been successfully used for the isolation and purification of 10 quinolones from chicken muscle tissue. The optimized immunoaffinity column sample cleanup procedure combined with HPLC coupling to fluorescence detection afforded low limits of detection (0.1 ng g(-1) for danfloxacin and 0.15 ng g(-1) for all other quinolones tested). The method was also applied to determine quinolone residues in commercial muscle samples.

Abstract
6-Methoxy-4-quinolone (6-MOQ, 1), an oxidation product derived from 5-methoxyindole-3-acetic acid, is a novel fluorophore, which has several useful characteristics for biomedical analysis. Compound 1 has strong fluorescence with a large Stokes' shift in aqueous media, and the maximum fluorescence excitation and emission wavelengths are 243 nm and 374 nm, respectively. The molar absorptivity at the maximum excitation wavelength and fluorescence quantum yield in aqueous 10% (v/v) methanol are 32 600 L mol(-1) cm(-1) and 0.38, respectively. The fluorescence intensity of 1 is scarcely affected by changing the medium pH, showing strong fluorescence from pH 2.0 to 11.0. In addition, 1 is highly stable against light and heat, and no degradation was observed at 60 degrees C for 3 days with exposure to daylight. As a fluorescent labeling reagent, [(6-methoxy-4-oxo-1,4-dihydroquinolin-3-yl)methyl]amine (6-MOQ-NH2, 2) was synthesized, and determination of carboxylic acids was demonstrated; 50 pmol of standard propionic acid and isobutyric acid were derivatized, and the obtained S/N ratios for 10 fmol (injection amount) of these two acids were 206 and 164, respectively.

Abstract
OBJECTIVE To develop a simple and sensitive high performance liquid chromatography method for the determination of ciprofloxacin concentrations in human serum and urine. METHOD Serum proteins were removed by ultrafiltration through a filtering device after the addition of a displacing reagent. Urine samples were diluted with mobile phase prior to injection. Separation was achieved with a C18 reverse-phase column and using ultraviolet (UVD) and fluorescence detection (FD) for serum samples and UVD for urine samples. RESULTS The quantitation limits of the assay were 20 ng/ml (FD) and 100 ng/ml (UVD) in serum and 1 microg/ml in urine. The assay was successfully applied to a pharmacokinetic study of ciprofloxacin in healthy volunteers. CONCLUSION The method presented for ciprofloxacin assay in human serum and urine requires less sample clean up and is more sensitive than those reported in the literature.

Abstract
Immunoaffinity solid-phase extraction (SPE) technique is based upon a molecular recognition mechanism. The high affinity and the high selectivity of the antigen-antibody interactions allow the specific extraction and the concentration of the analytes of interest in one step. In pharmaceutical and biological fields, where most often matrices are complex and analytes at trace-levels, this approach constitutes a unique tool for fast and solvent-free sample preparation. This review presents a general description of this extraction technique and gives numerous examples of its applications in pharmaceutical and biomedical fields. It emphasizes the on-line coupling with chromatographic and electrophoretic separation techniques and introduces new developments. The future directions, especially with regards to the current development of analytical microsystems, are discussed.

Abstract
A selective, sensitive and accurate liquid chromatographic method with UV and fluorescence detection was developed, validated and applied for the determination of fluoroquinolones in human plasma. The effects of mobile phase composition, ion-pair and competing-base reagents, buffers, pH, and acetonitrile concentrations were investigated on the separation of six quinolones (cinoxacin, levofloxacin, ciprofloxacin, gatifloxacin, moxifloxacin and trovafloxacin). Sample preparation was carried out by adding internal standard and displacing agent and processing by ultrafiltration. This method uses ultraviolet and fluorescence detection and separation using a C(18) column. The recovery, selectivity, linearity, precision, and accuracy of the method were evaluated from spiked human plasma samples. The method was successfully applied to patient plasma samples in support of a levofloxacin pharmacokinetic study.
