Article Title: YKL-40 protein expression in human tumor samples and human tumor cell line xenografts: implications for its use in tumor models
doi: 10.1007/s13402-021-00630-z
Figure Lengend Snippet: Representative YKL-40 immunostaining results of adjacent stroma in mouse xenograft tumor tissues (a–c) and human tumor samples (d–f) . Extracellular matrix components and stroma cells were identified morphologically. a Head and neck squamous cell cancer cell line UT-SCC-16A, b melanoma cell line FEMX-1, c pancreatic cancer cell line BxPC-3, d breast cancer, phyllodes subtype, e squamous cell esophageal cancer, f squamous cell lung cancer. Arrowheads point to fine granular staining in extracellular matrix components (mouse xenograft tumor tissue, a–c ) or small nucleated cells residing in adjacent tumor stroma and surrounded by fine granular staining (human tumor samples, d–f ). Scale bars = 50 µm
Article Snippet: Directly afterwards, sections were incubated with an anti-YKL-40 primary monoclonal mouse antibody (MAb 201.F9, 2.1 mg/ml, IgG2b, epitope GAWRGTTGHHS, aa 210–220) diluted 1:100 in antibody diluent (#S0809, Dako, Carpinteria, CA, USA) for 60 min at RT.
Techniques: Immunostaining, Staining
