We used biochemical fractionation, immunoassays and microscopy of live and fixed Acanthamoeba to determine how much profilin is bound to its known ligands: actin, membrane PIP(2), Arp2/3 complex and polyproline sequences. Virtually all profilin is soluble after gentle homogenization of cells. During gel filtration of extracts on Sephadex G75, approximately 60% of profilin chromatographs with monomeric actin, 40% is free and none voids with Arp2/3 complex or other large particles. Selective monoclonal antibodies confirm that most of the profilin is bound to actin: 65% in extract immunoadsorption assays and 74–89% by fluorescent antibody staining. Other than monomeric actin, no major profilin ligands are detected in crude extracts. Profilin-II labeled with rhodamine on cysteine at position 58 retains its affinity for actin, PIP(2) and poly-L-proline. When syringe-loaded into live cells, it distributes throughout the cytoplasm, is excluded from membrane-bounded organelles, and concentrates in lamellapodia and sites of endocytosis but not directly on the plasma membrane. Some profilin fluorescence appears punctate, but since no particulate profilin is detected biochemically, these spots may be soluble profilin between organelles that exclude profilin. The distribution of profilin in fixed human A431 cells is similar to that in amoebas. Our results show that the major pool of polymerizable actin monomers is complexed with profilin and spread throughout the cytoplasm.

ABSTRACTThree direct fluorescent-antibody staining assay kits for the detection of zoonoticCryptosporidiumspecies were used to detectCryptosporidium molnarifrom Murray cod, and the cryptosporidia were characterized by using small-subunit (SSU) ribosomal DNA (rDNA). To facilitate rapid diagnosis of infection, this study demonstrated that all three kits detected freshC. molnariand two kits detected formalin-fixed oocysts.

The intralobular distribution of nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome c (P-450) reductase (NADPH:ferricytochrome oxidoreductase, EC 1.6.2.4) in rat liver has been investigated by means of two quantitative immunohistochemical techniques: microdensitometric quantitation of unlabeled antibody peroxidase-antiperoxidase staining and microfluorometric analysis of indirect fluorescent antibody staining. Utilizing sheep antiserum elicited against NADPH-cytochrome c (P-450) reductase that had been isolated and purified to apparent homogeneity from rat liver microsomes, the reductase was detected within hepatocytes throughout the liver. However, differences in the intensity of staining of hepatocytes within different regions of the liver lobule were readily apparent after completion of both immunohistochemical staining procedures. These visual findings were verified by microdensitometric and microfluorometric analyses of immunohistochemical staining, both of which revealed that approximately the same degree of staining for NADPH-cytochrome c (P-450) reductase was produced within the centrilobular and midzonal regions of the liver lobule, whereas periportal hepatocytes were stained with significantly less intensity. These results demonstrate that the application of either microdensitometry in conjunction with unlabeled antibody peroxidase-antiperoxidase staining or microfluorometry after indirect fluorescent antibody staining can be used to quantitatively determine the intratissue distributions of antigens.
