By use of the indirect immunoperoxidase method, the brain, the suboesophageal ganglion and the corpora cardiaca of the dragonfly Aeschna cyanea have been shown to be immunoreactive to proctolin antiserum and to several mammalian peptide antisera incl

The following conclusions can be drawn from our studies: (1) An optimum molecular weight (Mn=2095) exists for t-octylphenol-formaldehyde resin to give maximum autohesion to rubber compounds. A critical level of the phenolic resin is required in a giv

Cells immunoreactive to antibodies raised against human pancreatic growth hormone releasing factor 1–44 −NH 2 (hp GRF) were detected in the brain and the suboesophageal ganglion of an insect. The presence of immunoreactive deposits within the ins

Two new methods of sample preparation have been developed for electron microscopical examination of polymer blends. The first is an ebonite method where the blend is hardened in a sulfur-sulfenamide-zinc stearate mixture and then microtomed. The seco

This work reports a direct surface analysis of ozonization of vulcanized NR compounds by ATR. On ozonization of a vulcanized NR compound without clay filler or AO a degraded rubber layer, which contains ozonides and carbonyl compounds, is formed on t

Single crystals of POAHP II were grown from acetic anhydride, a solvent in which POAHP I is thought to be stable. The single crystals gave an electron diffraction pattern which specified a hexagonal unit cell and the lateral spacing between molecular

Spherulites of poly-L-proline II were grown by film casting from a dilute formic acid solution. Electron diffraction indicated that the molecular axis was parallel to the surface and essentially normal to the face of the lamellae. The molecular lengt

The haemolymph ecdysteroid level after injection of ecdysone or ecdysterone inAeshna cyanea larvae has been determined by a radioimmunoassay method. The rate of excretion appears to be dependent on both the ecdysteroid injected and the time of inject
