Rhythmic Banding of Precipitates (liesegang’s Rings)
Rhythmic banding of precipitates was first discussed by Raphsel E. Liesegang (1)) hence the name “Liesegang’s rings.” He observed that when a solution of silver nitrate is placed on a gelatine gel containing dilute potassium bichromate, rhythmic banding of the precipitate occurs. If the solutions are in a dish or on a plane surface the precipitate is in concentric rings; if in a test-tube, supe...
متن کاملStudies on the mechanism of solubilization of immune precipitates by serum
Antigen (Ag)-antibody (Ab) aggregates prepared with several different antigens are solubilized by fresh serum at 37 degrees C (complex-release activity of serum or CRA). The rate of solubilization varies in different systems and is strongly influenced by the affinity of Ab for the Ag in the immune precipitate. With a given Ag-Ab precipitate, the maximum amount of complex that can be solubilized...
متن کاملStudies on the Mechanism of Solubilization of Immune Precipitates by Serum* by Joyce Czop Xnd
Immune precipitates formed by bovine serum albumin (BSA) I and antibodies to BSA dissolve rapidly when incubated in fresh serum (1). The solubilized complexes are aggregates of antigen (Ag), antibody (Ab), and complement (C) components (C3). The involvement of C in this activity of serum (complexrelease activity or CRA) was postulated because treatments that destroyed C in serum also removed CR...
متن کاملThe Adsorption of SDS on Ferro-Precipitates
The main aim of the paper is to evaluate ferroprecipitates as immobilization agents for removing selected surfactants from aqueous solutions. Two ferro-precipitates based on iron oxides were used. Adsorbents were varied both in elementary composition and mineral composition. Sodium dodecyl sulphate (SDS) was used as a model anionic surfactant. Simultaneous measurements of the surfactant’s adsor...
متن کاملNew insights into rhythmic brain activity from TMS-EEG studies.
There is renewed interest in the functional role of oscillatory brain activity in specific frequency bands, investigated in humans through electroencephalography (EEG) and magnetoencephalography (MEG) recordings. In parallel, there is a growing body of research on non-invasive direct stimulation of the human brain via repetitive (rhythmic) transcranial magnetic stimulation (TMS), and on those f...
