Somatostatin in human pancreatic and gastric juice
(Elsevier, 1981)
Considerable amounts of IRS are secreted after secretin injection in human pancreatic juice collected during endoscopic retrograde cholangiopancreatography. The mean IRS levels in the pancreatic juice of non-diabetic ...
Recent Advances in RNA Structure Determination by NMR
(John Wiley & Sons, 2000-10)
Despite recent advances in the solution of NMR structures of RNA and RNA‐ligand complexes, the rate limiting step remains the gathering of a large number of NOE and torsion restraints. Additional sources of information for ...
Synthesis and properties of 35S, 14C and 3H labeled S-alkyl glycerol ethers and derivatives
(Elsevier, 1976-07)
Radioactive S-alkyl glycerol ethers have been synthesized with 35S, 14C and 3H labels as well as 3H/35S double labels.The synthesized compounds were converted to various derivatives which can serve to characterize the ...
A chemical approach to solving bridging phenomena in steroid radioimmunoassays
(Elsevier, 1981-08)
Steroid radioimmunoassays (RIA) employ antibodies raised against a carrier protein-steroid conjugate. Individual antibodies may recognize the steroid, the protein or the chemical bridge used to Join them together. Use of ...
Rat liver membrane preparations
(Elsevier, 1972-09)
The quality of rat liver plasma membranes was examined using three different methods of preparation. Hypotonic Ca++-free preparation media were compared with hypotonic Ca++ media and with isotonic Ca++ media. The plasma ...
Regional processing of the N- and C-terminal domains of proopiomelanocortin in monkey pituitary and brain
(Elsevier, 1988-04)
The total content and extent of processing of the [gamma]3MSH and [beta]-endorphin-containing N- and C-terminal domains of proopiomelanocortin were determined in the anterior and intermediate lobes of the pituitaries and ...
Pharmacophore elements of the TIPP class of delta opioid receptor antagonists
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1994-10)
A series of tri-and tetrapeptides sharing the amino-terminal dipeptide unit Tyr-Tic, found in the high-affinity delta opioid receptor antagonist Tyr-Tic-Phe-Phe (TIPP), was prepared and evaluated in receptor binding assays ...
A reagent for covalently attaching biotin to proteins via a cleavable connector arm
(Elsevier, 1982-10-01)
The preparation of a reagent which can be used to attach biotin to proteins via a cleavable connector arm is described. The reagent, 3-(4-(N-biotinoyl-6-aminocaproyloxy)phenyl)propionic acid N-hydroxysuccinimide ester ...
Analysis of Oxidized DNA Fragments by Gel Electrophoresis
(Wiley Periodicals, Inc., 2001-04)
Polyacrylamide gel electrophoresis is used to define and quantify products of deoxyribose oxidation in DNA, based on the unique electrophoretic mobility of DNA fragments possessing deoxyribose oxidation products on their ...
NMR Determination of Oligonucleotide Structure
(Oxford University PressWiley Periodicals, Inc., 2000-02)
This unit provides an overview of the use of NMR to determine oligonucleotide structure. It covers basic NMR spectral properties, acquisition of interproton distance restraints and torsion angle restraints, structure ...
