Resolution of rabbit polyclonal anti-fluorescein Fab (IgG) fragments into subpopulations differing in affinity and spectral properties of bound ligand.Fab fragments derived from ten different IgG populations of hyperimmune rabbit polyclonal anti-fluorescein antibodies were further resolved into subfractions based on differences in time-dependent dissociation from an FITC-adsorbent in the presence of 0.1 M fluorescein at 4 degrees C. Fab fragments separated into subpopulations based on specific dissociation times of 0.1 day, 1.0 day, 10 days and 100 days from the adsorbent. Finally, after the 100 days elution step incubation with 6.0 M guanidine-HCl was included to determine total protein concentration of specific anti-fluorescein Fab fragments. Yields of specifically eluted Fab fragments ranged from 12.7 to 84.1% of the total Fab population originally incubated with the adsorbent. All Fab polyclonal populations and subpopulations analyzed quenched the fluorescence of the bound ligand by 90% or greater. None of the plots of protein concentration versus percent yield of the total specific antibody obtained for each of the five resolved fractions constituting a specific polyclonal population conformed to Gaussian distributions. All resolved Fab subpopulations retained bound fluorescein ligand that exhibited significant bathochromic shifts in absorbancy. Based on the extent of the red-shift the antibodies segregated into one of two general spectral families showing either a peak shift to 505-507 nm or to 518-520 nm. The red-shift to 518-520 nm appeared unique to rabbit anti-fluorescein antibodies, since corresponding large shifts have not been observed with antibodies derived from other species (e.g. mouse, rat, chicken, etc.). K(d) values determined for the resolved fractions confirmed a continuous progression in affinity from the 0.1day through the 100 days elution. Preliminary isoelectric focusing analyses revealed progressive selection for relatively more homogeneous fractions, especially in the 100 days resolved fraction.

Immunohistochemical localization of carbonic anhydrase IV in capillaries of rat and human skeletal muscle.We used polyclonal antisera raised in rabbits against membrane-bound rat lung and human lung carbonic anhydrase (CA) IV in immunofluorescence studies to stain cryosections of rat soleus and extensor digitorum longus (EDL) and several human skeletal muscles. There was strong specific staining of capillaries in all muscles investigated. Several techniques were applied to verify this result. (a) Serial sections were either incubated with anti-CA IV/FITC or processed for endothelial ATPase reaction. There was precise co-localization of antibody marked structures and ATPase stained capillaries. (b) Human muscle sections were double stained with anti-CA IV/TRITC and anti-von Willebrand factor (vWF)/FITC. vWF, a capillary marker, and CA IV were localized at identical sites. (c) The CAIV was released from capillaries by treatment with phosphatidylinositol specific phospholipase C, suggesting that the enzyme is anchored to the endothelial cell membrane via a phosphatidylinositolglycan anchor. (d) A rat hindlimb was perfused with diluted antiserum. Cryosections of perfused soleus and EDL processed for anti-rabbit IgG/FITC staining showed clear fluorescence associated with capillaries, indicating that the antigen was accessible from the capillary lumen. (e) Immune complexes formed during antiserum perfusion as described in d were precipitated from muscle homogenates. SDS-PAGE followed by immunoblotting showed that the predominant portion of total muscle CA IV was bound in these complexes and therefore must be located intravascularly.

A particle concentration fluorescence immunoassay for prostaglandin D synthase in the rat central nervous system.A solid phase, particle concentration fluorescence immunoassay (PCFIA) was developed for the measurement of prostaglandin (PG) D synthase in the 100,000g supernatant of various regions of the rat central nervous system. In this assay, the enzyme (in the range of 1-25 micrograms protein of brain supernatant or 1-100 ng of the purified enzyme) is attached to submicrometer carboxypolystyrene beads coated with polyclonal anti-rat brain PGD synthase IgG. The total particle-bound enzyme is assayed with fluorescein isothiocyanate (FITC)-conjugated monoclonal anti-PGD synthase IgG after incubation for 1 h. The optimum assay condition was obtained when carboxyl particles coated with ca. 500 micrograms/ml of polyclonal IgG at pH 5.0 and 5 micrograms/ml of FITC-IgG were used. No significant fluorescence was observed when FITC conjugates or carboxyl particles were prepared using IgG from nonimmunized rabbits. Heat treatment of the brain supernatant decreased the specific binding of the enzyme in parallel with the loss of enzyme activity, indicating that the denatured enzyme is not recognized by this assay method. The PGD synthase immunoreactivity was widely distributed in the brain regions and was highest in the paraflocculus. Although slight discrepancy was observed between the concentration by PCFIA and the enzyme activity measured by using [14C]PGH2 in some brain regions, there is a considerable correlation (0.727) between the values by both methods in the same brain regions. The PCFIA now developed showed higher sensitivity (around 10 times), greater reliability, and larger number of samples measurable at once than the radio-TLC assay using [14C]PGH2. This method could provide valuable information concerning the regulatory mechanisms of PGD synthase.
