Production and Evaluation of Polyclonal Rabbit Anti-Human p53 Antibody Using Bacterially Expressed Glutathione S-transferase-p53 fusion protein
p53 is a key tumor suppressor gene that is targeted for inactivation during human tumorigenesis. In this study, we produced and characterized polyclonal antihuman p53 antibody. The cDNA encoding the completehuman p53 protein was cloned into pGEX-4T-1 and expressed in Escherichia coli as a fusion protein with Schistosoma japonicum glutathione S-transferase (GST). The rabbits were immunized...
متن کاملDense-granule protein NcGRA7, a new marker for the serodiagnosis of Neospora caninum infection in aborting cows.
To investigate whether the production of an antigen-specific antibody is associated with Neospora caninum-induced bovine abortion, 62 serum samples were tested with an enzyme-linked immunosorbent assay using the recombinant antigens NcSAG1, NcSRS2, and NcGRA7. Our study suggested that NcGRA7 would be a new marker for the serodiagnosis of N. caninum infection resulting in abortion.
متن کاملEnzyme-Linked Immunosorbent Assay of Progesterone in Serum Using Penicillinase as Label
An enzyme-linked immunosorbent assay (ELISA) for progesterone measurement in serum or plasma samples using penicillinase as label enzyme is reported. A C3 and C11 derivatives of progesterone were prepared and conjugated to bovin serum albumin (BSA). Polyclonal antibody against these two immunogens were prepared in New Zealand white rabbits. Purified Ig fractions of antibodies were immobilized o...
متن کاملEvaluation of recombinant antigens in combination and single formula for diagnosis of feline toxoplasmosis.
Cats are the only definitive hosts of Toxoplasma gondii and constitute an essential source of infection to all warm blooded animals and humans. Diagnosis of T. gondii infection in cats is fundamental for proper management and control of infection in humans and animals. In the current study, we have evaluated the diagnostic performance of tachyzoite lysate antigen (TLA) and different T. gondii r...
متن کاملDevelopment of a diagnostic method for neosporosis in cattle using recombinant Neospora caninum proteins
BACKGROUND Neosporosis is an infectious disease primarily of cattle and dogs, caused by intracellular parasite, Neospora caninum. Neosporosis appears to be a major cause of abortion in dairy cattle worldwide and causes to huge economic loss to dairy industry. RESULTS Recombinant surface associated antigen 1 (NcSAG1), NcSAG1 related sequence 2 (NcSRS2) and the dense granule antigen 2 (NcGRA2) ...
