    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 35 kDa
    Observed band size : 50 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 11 kDa (possible non-specific binding),48 kDa (possible cleavage fragment),95 kDa (possible non-specific binding).

    Exposure time : 2 minutes

    FSTL1 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.

    The band observed at 48 kDa could potentially be a cleaved form of FSTL1 due to the presence of a 20amino acid signal peptide.

    This blot was produced using a 10% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab111969 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
