    Immunohistochemical analysis of paraffin-embedded human spleen  tissue labeling YKL-40/CHI3L1 with ab255297 at 1/250 dilution followed by ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on neutrophils of human spleen is observed.

    The section was incubated with ab255297 for 30 mins at room temperature.

    The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin.

    Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution) for 20mins.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab255297).

    Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol permeabilized THP-1 (human monocytic leukemia cell line) cells labelling YKL-40/CHI3L1 with ab255297 at 1/500 dilution (Red) compared with a Rabbit monoclonal IgG (ab172730, Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue).

    Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.

    Predicted band size: 43 kDa
    Observed band size: 42 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 27 kDa. We are unsure as to the identity of these extra bands.


    Exposure time: 60 seconds


    Blocking/Diluting buffer and concentration: 5% NFDM/TBST.

    The expression profile observed in 293T and Jurkat are consistent with the literature (PMID: 19767768,PMID: 16472595).
