Evaluation of an in-house indirect enzyme-linked immunosorbent assay of feline panleukopenia VP2 subunit antigen in comparison to hemagglutination inhibition assay to monitor tiger antibody levels by Bayesian approach.
Feline panleukopenia virus (FPV) is an etiologic pathogen of feline panleukopenia that infects all members of Felidae including tigers (Panthera tigris). Vaccinations against FPV among wild felid species have long been practiced in zoos worldwide. However, few studies have assessed the tiger immune response post-vaccination due to the absence of a serological diagnostic tool. To address these limitations, this study aimed to develop an in-house indirect enzyme-linked immunosorbent assay (ELISA) for the monitoring of tiger antibody levels against the feline panleukopenia vaccine by employing the synthesized subunit capsid protein VP2. An in-house horseradish peroxidase (HRP) conjugated rabbit anti-tiger immunoglobulin G (IgG) polyclonal antibody (HRP-anti-tiger IgG) was produced in this study and employed in the assay. It was then compared to a commercial HRP-conjugated goat anti-cat IgG (HRP-anti-cat IgG). Sensitivity and specificity were evaluated using the Bayesian model with preferential conditional dependence between HRP-conjugated antibody-based ELISAs and hemagglutination-inhibition (HI) tests.Chanakan Areewong, Amarin Rittipornlertrak, Boondarika Nambooppha, Itsarapan Fhaikrue, Tawatchai Singhla, Chollada Sodarat, Worapat Prachasilchai, Preeyanat Vongchan, Nattawooti Sthitmatee

Evaluation of a 14.5 kDa-Fasciola gigantica fatty acid binding protein as a diagnostic antigen for human fascioliasis.
The aim of the present study was to evaluate the efficiency of 14.5 kDa-Fasciola gigantica fatty acid binding protein (FABP) as a diagnostic antigen for human fascioliasis. 14.5 kDa FABP was isolated from the crude extract of adult F. gigantica worms by ion exchange chromatography followed by gel filtration chromatography and then analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis under reducing condition. Anti-FABP IgG polyclonal antibody (pAb) was generated in rabbits and purified by using sequential use of ammonium sulfate, caprylic acid, and then ion exchange chromatography. Conjugation of purified rabbit anti-FABP IgG with horse reddish peroxidase (HRP) was conducted and used in detecting the coproantigen in the stool and the circulating Fasciola antigen (CA) in the sera of Fasciola-infected patients using sandwich enzyme-linked immunosorbent assay (ELISA). The sensitivities of sandwich ELISA test were 96.43% and 94.74%, while the test specificities were 94.87% and 84.62% for the detection of coproantigen and CA, respectively. The parasitological diagnosis using the Kato-Katz technique revealed 64.29% sensitivity with 100% specificity. The diagnostic efficacy of sandwich ELISA was 95.52% for coproantigen and 87.93% for CA detection. In contrast, the diagnostic efficacy of Kato-Katz technique was 85.07%. It was concluded that 14.5 kDa FABP represented a valuable antigen for the immunodiagnosis of human fascioliasis using sandwich ELISA.Gamal Allam, Ibrahim R Bauomy, Zeinab M Hemyeda, Thabet F Sakran

Nanotube-based colorimetric probe for ultrasensitive detection of ataxia telangiectasia mutated protein.
We have developed a nanotube-based colorimetric probe using multiwalled carbon nanotubes (MWNTs), anti-immunoglobulin G (anti-IgG), and horseradish peroxidase (HRP). The probe was used as an alternative to conventional colorimetric conjugates to obtain amplified signals in a sandwich-type immunoassay for ataxia telangiectasia mutated (ATM), a potential biomarker for radiation doses and cancers. Results show that the MWNT-based probe colorimetry was 5000 times more sensitive than a conventional ELISA, while its concentration range was 10,000 times wider than that of the latter. Its limit of detection (LOD) was 0.2 fg/mL (54 aM, ~32 molecules in 1 μL samples). Control experiments showed that detection of ATM molecules at the picogram-level could still be achieved in samples that contained protein makers present at more than 100 times the ATM concentration, demonstrating the high specificity of the technique. The MWNT-based probe also has the potential to become a universal probe for colorimetric assays of most protein markers because it can recognize the associated rabbit polyclonal antibodies.Qingzhi Zhang, Bin Zhao, Juan Yan, Shiping Song, Rui Min, Chunhai Fan

Validated enzyme-linked immunosorbent assay for determination of rosuvastatin in plasma at picogram level.
In this study, a highly sensitive enzyme-linked immunosorbent assay (ELISA) has been developed and validated for the determination of rosuvastatin (ROS) in plasma samples at picogram level. The assay employed a polyclonal antibody that specifically recognizes ROS with high affinity, and ROS conjugate of bovine serum albumin (ROS-BSA) immobilized onto microplate wells as a solid phase. The assay involved a competitive binding reaction between ROS, in plasma sample, and the immobilized ROS-BSA for the binding sites on a limited amount of the anti-ROS antibody. The bound anti-ROS antibody was quantified with horseradish peroxidase-labelled second anti-rabbit IgG antibody (HRP-IgG) and 3,3`,5,5`-tetramethylbenzidine (TMB) as a substrate for the peroxidase enzyme. The concentration of ROS in the sample was quantified by its ability to inhibit the binding of the anti-ROS antibody to the immobilized ROS-BSA and subsequently the colour intensity in the assay wells. The assay limit of detection was 25 pg ml(-1) and the effective working range at relative standard deviations (RSD) of ≤ 5% was 40-2000 pg ml(-1). Analytical recovery of ROS from spiked plasma was 96.2 - 104.8 ± 2.12 - 5.42%. The precision of the assay was satisfactory; RSD was 2.47 - 4.46 and 3.24 - 5.27% for the intra- and inter-assay precision, respectively. The analytical procedure is convenient, and one can analyze ~ 200 samples per working day, facilitating the processing of large-number batch of samples. The proposed ELISA has a great value in routine analysis of ROS for its pharmacokinetic studies.Ibrahim A Darwish, Abdul-Rahman M Al-Obaid, Hamoud A Al-Malaq

An antibody chimera technique applied to enzyme immunoassay for human alpha-1-fetoprotein with monoclonal and polyclonal antibodies.
A 2-step enzyme immunoassay (EIA) for human alpha-1-fetoprotein (AFP) is proposed, which uses covalently coupled anti-AFP IgG and anti-horseradish peroxidase (HRP) IgG (antibody chimera) binding HRP as the marker enzyme immunologically. The use of polyclonal and monoclonal anti-AFP linked to anti-HRP antibodies was compared with a conventional 2-site binding EIA with HRP covalently bound to anti-AFP IgG. The sensitivity of the conventional EIA is increased by the use of an antibody chimera comprising a molar ratio of anti-AFP IgG: anti-HRP IgG of 1:8, especially if monoclonal antibodies are employed. This improved sensitivity may be achieved by a very simple coupling procedure without purification of conjugate and with very crude HRP preparations.B Porstmann, S Avrameas, T Ternynck, T Porstmann, B Micheel, J L Guesdon
