Human Capping Protein Muscle Z Line Beta (CAPZb) ELISA Kit

The CAPZb subunit of the heterodimeric F-actin capping protein anchors the barbed ends of actin filaments at the sarcomeric Z-disc, where it controls filament length and contractile efficiency in striated muscle. The Assay Genie kit provides a quantitative in vitro immunoassay for measuring this cytoskeletal regulator in cell lysates and tissue homogenates derived from human samples.

Investigators studying sarcomere assembly, cardiomyopathy, nemaline myopathy, and cytoskeletal remodeling can use the plate-based workflow to compare CAPZb expression across patient biopsies, gene-edited models, and drug-treated cultures. The assay is supplied in a microplate configuration accommodating up to 96 sample determinations per run alongside a standard curve on a single plate.

Each kit ships with the components required to complete the protocol, and absorbance is read on standard microplate readers commonly found in research laboratories.
