pcp-1 Antibody

Introduction to PCP-1 Antibody

The PCP-1 antibody targets Bone Morphogenetic Protein 1 (BMP1), also known as Procollagen C-Proteinase (PCP), a zinc-dependent metalloprotease critical for extracellular matrix (ECM) maturation. This enzyme processes precursor proteins like collagens, laminins, and lysyl oxidase into functional forms, enabling tissue remodeling and repair . Antibodies against BMP1/PCP are pivotal tools for studying ECM dynamics, cancer progression, and developmental biology.

Key Antibody Clones

• Specificity: Western blot validation confirms reactivity with human, mouse, and rat BMP1/PCP. For example, ab205394 detects a 111 kDa band in PC12 and human liver lysates .

• Cross-reactivity: No binding observed with homologous proteins like ADAM10, ADAMTS4, or MMP-1 .

Functional Insights from Key Studies

• Cancer Research:

  • In clear cell renal cell carcinoma (ccRCC), BMP1 knockdown via shRNA reduced proliferation, migration, and invasion of A498 and Caki-1 cells .

  • Immunohistochemistry revealed upregulated BMP1 expression in ccRCC tissues compared to normal controls .

• ECM Studies:

  • BMP1/PCP antibodies localize cytoplasmic expression in human kidney convoluted tubules .

Technical Performance

• Western Blot: Optimal detection at 1 µg/mL (ab205394) or 0.1 µg/mL (AF1927) with chemiluminescence .

• Immunohistochemistry: Effective in paraffin-embedded tissues using antigen retrieval protocols .

Mechanistic Insights

• BMP1/PCP silencing disrupts ECM remodeling, impairing tumor cell motility and metastatic potential .

• Antibodies like AF1927 enable precise detection of BMP1 isoforms in developmental studies .

Limitations and Future Directions

• Species Specificity: Most antibodies detect human BMP1 but lack reactivity with murine isoforms .

• Therapeutic Potential: Targeting BMP1/PCP could mitigate fibrosis or metastasis, but in vivo efficacy studies remain limited .
