MyBioSource has introduced a Sheep anti-Rat Calretinin Polyclonal antibody to their collection, targeting the vital calretinin protein involved in neurobiology and cellular calcium signaling. This antibody, with 100% sequence homology, has potential cross-reactivity with mouse, human, and non-human primate calretinin, making it valuable for researchers in neurodegeneration, calcium signaling, and auditory neuroscience.
