Period Antibody (H-3) is a mouse monoclonal IgG2a kappa light chain antibody that detects period protein of Drosophila melanogaster origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Anti-period antibody (H-3) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Period protein functions as a DNA-binding transcription factor regulating circadian rhythms, which are essential for maintaining physiological processes that follow a roughly 24-hour cycle, such as sleep-wake patterns, hormone release, and metabolism. Disruptions in circadian rhythms can lead to various health issues, including sleep disorders, metabolic syndrome, and certain cancers, highlighting the significance of studying period protein in both basic biology and potential therapeutic interventions. Drosophila melanogaster serves as an invaluable model organism for investigating these processes, as many genetic and physiological similarities are shared with higher eukaryotes, making period protein research highly relevant to understanding circadian biology in humans.

Rated 1 out of 5 by from Bind still present in per[01] amorphSees a band of the 'right' size for wt Per.....but tried it on per[01] mutants, and the band is still there. The allele is a premature stop one-third of the way into the ORF, so the ab must not detect Per, just something of the same MW.

Rated 5 out of 5 by from The antibody has a high specificity.This kind of antibody is very popular, even if we 1:1000 this antibody dilution, we can still get a single strong band. This indicates that the antibody is highly specific.
