Enzyme-linked immunosorbent assay for quantitative determination of the visual pigment rhodopsin in total-eye extracts

Experimental Eye Research
J J Schalken, W J de Grip


A versatile, multispecies enzyme-linked immunosorbent assay for the rod visual pigment (rhod)opsin has been developed. For this quantitative inhibition assay a monospecific polyclonal antiserum is used which is elicited in rabbits against bovine rod outer-segment membranes. Detergent concentrations as high as 1.0% can be used in the assay with only a slight loss in sensitivity. The assay allows quantitative determination of the apoprotein opsin with a detection level of about 0.04 pmol per sample by using standards prepared by illumination of spectrophotometrically determined amounts of rhodopsin. The antiserum shows considerable cross-reactivity with opsin from several species (mouse, rat, quail, monkey and man). The high degree of monospecificity and cross-reactivity of the antiserum already allowed quantitation of opsin content in crude eye extracts of mouse, rat and quail with a sensitivity comparable to that of bovine opsin. Similar types of multispecies immunoassays for quantitation of highly conserved membrane proteins can be developed using the described approach, requiring only a monospecific antiserum elicited against an easily accessible species and crude tissue extracts both for coating and as a source of the inhibi...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
