Detection of 3-chlorinated tyrosine residues in human cells by flow cytometry.
Hypochlorite is a strong oxidant, generated under pathological conditions, with the potency to introduce chlorine atom into a number of molecules. 3-Chloro- and 3,5-dichlorotyrosine are documented to be generated by this oxidant and their elevated levels were found in many diseases. Thus, we decided to check the possibility of use of FITC-conjugated antibodies for flow cytometric detection of 3-chlorotyrosine residues in human cells (A549, MCF-7, HUVEC-ST) exposed to the action of hypochlorite. Additionally, we compared the effects of chlorohydrins and N-chloroamino acids as chlorine donors. Cell fixation and permeabilization was followed by incubation with rabbit polyclonal anti-3-chlorotyrosine primary antibody and subsequent staining with goat anti-rabbit FITC-labeled secondary antibody. For antibody isotypic control, normal rabbit IgG was employed. Hypochlorite appeared to be the most efficient from the chlorocompounds analyzed in chlorotyrozine generation in all cell lines. Statistically significant increase of fluorescence corresponding to the level of 3-chlorotyrosine residues was found in cells treated with hypochlorite even at non-toxic concentrations (<5μM). This effect was not observed in cells exposed to the action of chlorinated amino acids or chlorohydrins. The use of anti-3-chlorotyrosine antibodies in conjunction with fluorophore-conjugated secondary antibodies analysis allows for detection of 3-chlorotyrosine residues by flow cytometry in cells treated with low doses of hypochlorite.Agnieszka Robaszkiewicz, Grzegorz Bartosz, Miroslaw Soszynski

Detection of Xylella fastidiosa from resistant and susceptible grapevine by tissue sectioning and membrane entrapment immunofluorescence.
Immunofluorescence detection was performed by tissue sectioning and membrane entrapment of Xylella fastidiosa from the inoculated hybrid selection F8909-08 (Vitis rupestris A. de Serres x V. arizonica/candicans b43-17; resistant) and Chardonnay (susceptible). In both techniques, tissue sections and bacteria-trapped polycarbonate membranes were incubated with specific polyclonal IgG and stained with fluorescein isothiocyanate (FITC)-conjugated IgG from rabbits to X. fastidiosa cells. The stained preparations were observed by fluorescence microscopy. Rapid identification of the bacteria within 3 weeks post inoculation (wpi) was possible in thin cross sections of the petioles, which allowed penetration of the specific antibody. Examination of the bacteria over time was also possible, and allowed observation of bacterial multiplication and invasion of xylem vessels. The membrane entrapment technique was able to isolate bacteria at low concentrations in infected but asymptomatic plants.Nihal Buzkan, Lászlo Kocsis, M Andrew Walker

Removal of therapeutic anti-lymphocyte antibodies from human sera prior to anti-human leukocyte antibody testing.
Both monoclonal (e.g. Orthoclone (OKT3), rituximab) and polyclonal (e.g. ATGAM, Thymoglobulin (Thymo)) anti-lymphocyte Abs (ALAs) are used extensively in organ transplantation for immunosuppression induction, desensitization, and treatment of acute rejection. ALAs often interfere with post transplant immunologic monitoring. We describe a method that uses magnetic beads to selectively remove ALAs from patient serum. Rabbit anti-mouse Fc-specific (180 mug), or rabbit anti-mouse Fab-specific (180 microg), or rabbit anti-horse heavy and light chain-specific and rabbit anti-horse F(ab')2 (200 microg) (Jackson Immunoresearch) was adsorbed to 6.7 x 10(8) Dynabeads M-280 conjugated with sheep anti-rabbit IgG (Dynal Biotech). Fifty microliters of normal human serum (NHS) with 2 microg/ml of OKT3 or 100 microg/ml ATGAM, Thymo, or rituximab were incubated with conjugated beads for several incubations. NHS containing ALAs before and after treatment by the protocol were incubated with human lymphocytes and labeled with FITC-antibody to immunoglobulin of the species used to produce the particular ALA. Residual ALA was determined using flow cytometry. Average median channel for serum with or without ALA was 11.1 and 0.120, respectively for OKT3; 64.4 and 0.344 for ATGAM; 108.5 and 0.200 for Thymo; and 1022.5 and 11.4 for rituximab. Treatment lowered the median channel for serum with OKT3 to 0.103, 0.309 for ATGAM, 0.199 for Thymo, and 12.1 for rituximab. ALAs can be effectively removed from serum by the use of magnetic beads conjugated with Ab specific for ALA thereby permitting immunologic monitoring without interference.Christopher M Bearden, Benita K Book, Richard A Sidner, Mark D Pescovitz

Dual enhancement of triple immunofluorescence using two antibodies from the same species.
Triple immunofluorescence method with two mouse monoclonal antibodies and another rabbit polyclonal antibody was established with catalyzed reporter deposition (CARD) amplification on thick floating sections from the rat cerebellum. One of the monoclonal antibodies (anti-calbindin), diluted maximally, probed with anti-mouse IgG-horseradish peroxidase (HRP) and amplified with Cy5-conjugated tyramide, immunolabeled cerebellar Purkinje cells and their arborization. Subsequently, a rabbit polyclonal IgG (anti-glial fibrillary acidic protein (anti-GFAP)), probed with anti-rabbit IgG-HRP, amplified with biotin-tyramide and visualized with fluorescein-isothiocyanate (FITC)-streptavidin, immunolabeled Bergmann's glia. Another mouse monoclonal IgG (anti-SNAP25), probed with anti-mouse IgG-rhodamine without CARD amplification, selectively visualized synaptic sites, because the maximal dilution of the other monoclonal antibody (anti-calbindin) was below the detection threshold of this anti-mouse IgG-rhodamine. Separation of the two signals (calbindin and SNAP25), each detected through mouse monoclonal antibody, was then based on the difference of sensitivity either with or without CARD amplification. Triple immunofluorescence is possible when just one of the three primary antibodies is from different species. Intensification of two of the three signals provides further advantages to examine immunolocalization of multiple epitopes on histological sections.Ayako Nakamura, Toshiki Uchihara

In situ localization associates biologically active plant natriuretic peptide immuno-analogues with conductive tissue and stomata.
Plant natriuretic peptide immuno-analogues (irPNP) have previously been shown to affect a number of biological processes including stomatal guard cell movements, ion fluxes and osmoticum-dependent water transport. Tissue printing and immunofluorescent labelling techniques have been used here to study the tissue and cellular localization of irPNP in ivy (Hedera helix L.) and potato (Solanum tuberosum L.). Polyclonal antibodies active against human atrial natriuretic peptide (anti-hANP) and antibodies against irPNP from potato (anti-StPNP) were used for immunolabelling. Tissue prints revealed that immunoreactants are concentrated in vascular tissues of leaves, petioles and stems. Phloem-associated cells, xylem cells and parenchymatic xylem cells showed the strongest immunoreaction. Immunofluorescent microscopy with fluorescein isothiocyanate (FITC)-conjugated goat anti-rabbit IgG supported this finding and, furthermore, revealed strong labelling to stomatal guard cells and the adjacent apoplastic space as well. Biologically active immunoreactants were also detected in xylem exudates of a soft South African perennial forest sage (Plectranthus ciliatus E. Mey ex Benth.) thus strengthening the evidence for a systemic role of the protein. In summary, in situ cellular localization is consistent with physiological responses elicited by irPNPs reported previously and is indicative of a systemic role in plant homeostasis.M M Maryani, M V Morse, G Bradley, H R Irving, D M Cahill, C A Gehring
