Cytosolic fructose-1,6-biphosphatases (FBPase, EC 3.1.3.11) from pea (Pisum sativum L. cv Lincoln) and spinach (Spinacia oleracea L. cv Winter Giant) did not cross-react by double immunodiffusion and western blotting with either of the antisera raised against the chloroplast enzyme of both species; similarly, pea and spinach chloroplast FBPases did not react with the spinach cytosolic FBPase an...
Chemically synthesize carrier-bound peptides have been used as antigens in diagnostic test systems (ELISA) and for raising antipeptide-specific antisera. The method does not require prior cleavage of the peptides from the support used for the solid-phase synthesis. Using the same resin for both the synthesis and the subsequent applications it was possible to avoid expensive and time-consuming p...
An indirect method of an enzyme-linked immunosorbent assay (ELISA) is described to assess the reactivity of antisera used for the identification of peptide hormone producing cells by immunocytochemistry. Compared with radioimmunoassay and immunodiffusion, the ELISA method has the advantages of simplicity and sensitivity and represents with the hormone adsorbed to a matrix a situation more or le...
An enzyme-linked immunosorbent assay (ELISA) utilizing antigen coated on hydrophobic polyvinyldiene fluoride (PVDF) membranes is described for detecting antibodies that bind to squalene (SQE). Because of the prior lack of availability of validated antibodies to SQE, positive controls for the assay were made by immunization with formulations containing SQE to create monoclonal antibodies (mAbs) ...
BACKGROUND Veterinary drugs such as clenbuterol (CL) and sulfamethazine (SM2) are low molecular weight (<1000 Da) compounds, or haptens, that are difficult to develop immunoassays due to their low immunogenicity. In this study, we conjugated the drugs to ovalbumin to increase their immunogenicity for antiserum production in rabbits and developed a protein microarray immunoassay for detection of...
The N-terminal sequence of a mixture of desmosomal glycoproteins 2 and 3 (dg2/3, desmocollins) from bovine nasal epidermis, prepared by electro-elution from polyacrylamide gels, was determined by solid-phase Edman degradation. A sequence of 23 amino acids was obtained. This showed 43% identity with that of the N terminus of the calcium-dependent cell adhesion molecule, N-cadherin. A lesser degr...
Aspergillus oryzae is one of the common plant pathogens in wheat, sorghum and other crops. Its toxic activity has been proved. Hence, a sensitive, rapid, and inexpensive screening test to detect Aspergillus in agricultural commodities is necessary to protect human health. Aspergillus oryzae proteins were prepared, characterized, and used as an antigen. 6-month-old white albino rat were immunize...
Blattella germanica allergen 2(Bla g 2) gene was amplified by RT-PCR from total RNA of Blattella germanica and inserted into pET-41b vector properly. GST-Bla g 2 was expressed in E.coli via IPTG induction, a relative molecular mass of approximately 74kDa was showed by SDS-PAGE. The expressed fusion protein was purified by Ni+-agarose affinity chromatography, an emulsion was prepared with the pu...
Two peptides, related to the locust myotropic peptides locustatachykinin I-IV, were isolated from the blowfly Calliphora vomitoria. Whole, frozen flies were used for extraction with acidified methanol. A cockroach hindgut muscle contraction bioassay was used for monitoring fractions during subsequent purification steps. A series of eight different high performance liquid chromatography column s...
