Used in research settings to quantitatively measure Cyclin-D2 protein levels in rat biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit is particularly useful in studies related to cell cycle regulation, proliferation, and differentiation in neuronal and immune cells, where Cyclin-D2 plays a critical role. It supports investigation into diseases involving dysregulated cell cycle progression, including cancer and neurodegenerative disorders. The assay enables high sensitivity and specificity detection, allowing researchers to monitor changes in Cyclin-D2 expression under experimental conditions, assess the impact of therapeutic agents, and validate findings from genetic or pharmacological interventions.
