Primary antibodies used for immunohistochemical staining of paraffin embedded tissue were: anti-collagen IV and anti-α-smooth muscle actin (Abcam), anti-laminin 1 (R&D Systems), anti-mouse β1 integrin (Chemicon), anti-mouse F4/80 (Biolegend),, anti-human fibrinogen (Dako), and anti-mouse Plg-RKT, produced in our laboratory [15 (link)]. For immunohistochemistry of frozen sections, anti-Ser28-phosphorylated histone H3 was from Sigma.
Mouse prolactin and uPA ELISA kits and an ELISA kit recognizing both fibrinogen and fibrin species were from Innovative Research, Inc. The mouse D-dimer ELISA kit was from LifeSpan Bioscience. The hydroxyproline assay kit was from Cell Biolabs.
