PCOLCE Antibody, FITC conjugated

What is PCOLCE and what is its biological significance in collagen research?

PCOLCE (Procollagen C-Endopeptidase Enhancer) is a glycoprotein that plays a critical role in collagen maturation pathways. It binds to the C-terminal propeptide of type I procollagen and significantly enhances procollagen C-proteinase activity, which is essential for proper collagen fiber formation . The protein is also known by several alternative names including PCPE-1, Procollagen C-proteinase enhancer 1, and Type I procollagen COOH-terminal proteinase enhancer . PCOLCE represents an important target for researchers investigating extracellular matrix formation, fibrosis-related pathologies, and wound healing processes. The antibody targeting this protein provides valuable insights into collagen processing mechanisms and related cell signaling pathways.

What is the detailed specification profile of commercially available PCOLCE antibody, FITC conjugated?

The PCOLCE antibody, FITC conjugated, is typically characterized by the following specifications:

How should researchers optimize PCOLCE antibody, FITC conjugated for immunofluorescence applications?

When utilizing PCOLCE antibody with FITC conjugation for immunofluorescence studies, researchers should implement the following optimization protocol:
