It is synthesized as an inactive 43kDa preprocathepsin D that is cleaved and glycosylated to form a 46kDa procathepsin D and then further cleaved to produce 28kDa and 15kDa subunits (heavy and light chains, respectively). Cathepsin D exhibits pepsin-like activity and plays a role in protein turnover and in the proteolytic activation of hormones and growth factors. Mutations in this gene play a causal role in neuronal ceroid lipofuscinosis-10 and may be involved in the pathogenesis of several other diseases, including breast cancer and possibly Alzheimer's disease.\u003c\/p\u003e\u003cp\u003eThis anti-CTSD antibody is supplied as Purified (Mouse, Monoclonal (mouse origin), clone CTSD\/2781, Mouse IgG1, kappa, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.\u003c\/p\u003e\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget:\u003c\/strong\u003e CTSD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Purified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocalization:\u003c\/strong\u003e Cytoplasmic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecies reactivity:\u003c\/strong\u003e Human\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications (listed):\u003c\/strong\u003e IHC-P, WB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConjugate:\u003c\/strong\u003e Unconjugated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClone and antibody class:\u003c\/strong\u003e Monoclonal (mouse origin), clone CTSD\/2781, Mouse IgG1, kappa\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.\u003c\/p\u003e\u003ch2\u003eBiological background\u003c\/h2\u003e\u003cp\u003eCTSD is referenced in public gene\/protein resources (e.g., UniProt and NCBI Gene), which provide curated names\/synonyms, protein features, and pathway context.
