Known receptor

Methods of sulfate determination used in common practice suffer from essential disadvantages (time consumption, laboriousness, low sensitivity, etc.). For this reason, creation of sulfate-selective electrode suitable for direct potentiometric determination of this ion, has been attempted for a long time. Nowadays, nearly a dozen of sulfate-selective electrodes based on charged or neutral carriers of different stmcture have been described. Flowever, no known receptors for sulfate ions are available commercially. 

Homology screening. Using oligonucleotide probes based on known receptor sequences, search cDNA libraries for homologous sequences which may code for related receptors. The clones are then isolated and sequenced and used in expression studies to confirm the identity of the receptor. 

A well-known receptor of CT is ganglioside Gmi its chemical structure is Gal-p-(l-... 

Completely unknown. Salvia divinorum represents an entirely new class of entheogen. A Novascreen receptor site screening sponsored by David Nichols discovered no binding Inhibition for the forty reference compounds tested, covering all major known receptors. 

Shortly after discovering salvinorin A s effects, Siebert sent a sample to David Nichols who initiated a NovaScreenTM receptor site screening. The screening results were in contrast to those of all previously tested psychedelics. Salvinorin A did not affect any of the receptor sites tested, which included all of the likely known receptor sites for other psychedelics. 

One of the best known receptor units is that introduced by Hamilton et al. 

Positive controls are critical in PCR experiments. Positive controls can include spiking trace amounts of a plasmid for a known receptor into the PCR template. Negative controls can be a reaction mixture minus template.
