Aplysia abdominal ganglion neuron L5 is immunoreactive with an antiserum generated against the tetrapeptide Phe-Met-Arg-Phe-amide (FMRFamide); however, the specificity of this immune reagent is limited to the sequence Arg-Phe-amide. We isolated cDNA clones homologous to mRNAs specifically expressed in L5 and demonstrated that these clones do not hybridize(More)
We have developed a murine monoclonal antibody (mAb) specific for the delta chain of hemoglobin (Hb) A2 that does not cross-react with alpha, beta, or gamma chains. The mAb reacted with Hb P-Nilotic (beta delta hybrid), but not with Hb Lepore-Boston (delta beta hybrid), indicating an epitope consisting of positions 116 (Arg) and 117 (Asn) or 125 (Gln) and(More)
An antigen localized at the centriolar region has been identified by indirect immunofluorescence studies in African green monkey kidney, human, hamster, rat, and mouse cells. The antigen consists of two polypeptides of 14,000 and 17,000 daltons. A related antigen is also present at the basal body region in ciliated cells from chicken, cat, mouse, pig,(More)
BACKGROUND AND AIM Clitoria ternatea, a medicinal herb native to tropical equatorial Asia, is commonly used in folk medicine to treat various diseases. The aim of the present study is to evaluate the hepatoprotective and antioxidant activity of C. ternatea against experimentally induced liver injury. METHODS The antioxidant property of methanolic extract(More)
Transcription of the egg-laying hormone (ELH) gene family was examined by characterizing homologous cDNA clones from abdominal ganglion and atrial gland cDNA libraries. All cDNAs contain an exon that spans the coding region (exon III) and one or two additional exons. The tissue-specific expression of the ELH gene family was confirmed by the observation that(More)
The proteins of identified cells from the Aplysia californica central nervous system were labeled with radioactive amino acids and fractionated on SDS acrylamide gels containing 6 M urea. Most of the large cells contain prominent, cell-specific protein products in the molecular weight range between 3 and 30 KD. The molecular weights of the largest specific(More)
To facilitate the screening of blood for the presence of hemoglobins S or C, we devised an enzyme-linked immunoassay (ELISA). The ELISA procedure incorporated a murine monoclonal antibody (mAb), beta s-1, which recognized both Hb variants but did not react with Hb A, Hb A2 or Hb F. Hemoglobins in cord or adult hemolysates were coated on the surface of wells(More)
We have generated a murine hybridoma that secretes a monoclonal antibody (mAb) that is highly specific for hemoglobin C (HbC) [alpha 2 beta 2 6(A3)Glu----Lys] and shows no cross reactivity with HbA, HbA2, HbF, HbS, HbE, or Hb O-Arab. Using this antibody, we developed a simple and rapid enzyme linked immunosorbent assay (ELISA) technique for the detection of(More)
A murine monoclonal antibody (mAb) was generated that recognizes hemoglobin (Hb) H, the tetrameric form (beta 4) of human beta-globin chains. The antibody beta 4-1 (gamma 1, kappa) does not react with Hbs A, F, Bart's, or isolated beta chains, indicating that the antibody recognizes an epitope comprised of multiple beta chains. A simple, rapid, and(More)
