Anti-DLK antibody 画像

    ab21682 staining DLK in human bone marrow within the haemopoietic tissue and not the adipocytes. Paraffin embedded human bone marrow was incubated with ab21682 (1/150 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.

    ab21682 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further results for this antibody can be found at www.proteinatlas.org.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 41 kDa
    Observed band size : 45,48 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 15 kDa (possible cleavage fragment),55 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 3 minutes

    This blot was produced using an 8% Tris-glycine gel under the Tris-glycine buffer system. The gel was run at 120V for 1 hour 15 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Milk before being incubated with ab21682 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

  • Immohistochemical analysis of formaldehyde-fixed paraffin-embedded human placental tissue sections, labelling DLK with ab21682 at a dilution of 1/1000 incubated for 20 minutes at 25°C. Blocking was with hydrogen peroxide at 3% incubated for 10 minutes at 25°C. The secondary used was a gekko ant-rabbit polyclonal HRP conjugate used undiluted.
