Mouse lungs were perfused and inflated with 20 ml/kg aqueous buffered zinc formalin (Z-FIX; Anatech, Battle Creek, MI) immediately following euthanasia and used for paraffin-embedding. Immunofluorescence staining was performed as described previously (Lee et al., 2017 (link)). Paraffin-embedded tissue sections (5 μm) were rehydrated and subjected to antigen retrieval in Tris-HCl buffer (100 mM, pH 9.5). Blocking was performed with 15% BSA in 0.2% Triton-X/PBS at room temperature for 60 min. Sections were incubated with chicken anti-GFP (1:500, Abcam, ab13970) and goat anti-SP-C (1:50, Santa Cruz Biotechnology, sc-7706) overnight at 4°C. The immune complexes were detected using Alexa Fluor 568 donkey anti-goat or Alexa Fluor 488 goat anti-chicken (1:400, Invitrogen) secondary antibodies before sections were counterstained with DAPI. Sections were mounted in Prolong Gold antifade reagent (Invitrogen). Fluorescence images were acquired using a Zeiss microscope.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
