  • Relevance

    Chitinase 3 like protein 3: Lectin that binds saccharides with a free amino group, such as glucosamine or galactosamine. Binding to oligomeric saccharides is much stronger than binding to mono- or disaccharides. Also binds chitin and heparin. Has weak hexosaminidase activity but no chitinase activity. Has chemotactic activity for T-lymphocytes, bone marrow cells and eosinophils. May play a role in inflammation and allergy. Chitinase 3 like protein 4: Has low chemotactic activity for eosinophils. May play a role in inflammation and allergy. Has no chitinase activity.
  • Cellular localization

    Chitinase 3 like protein 3: Secreted. Rough endoplasmic reticulum lumen. Nucleus envelope. Cytoplasm. Cytoplasmic granule. Note: Predominantly localizes to the lumen of rough endoplasmic reticulum (rER) and nuclear envelope in alveolar macrophages. Localizes to the dilated lumen of rER in immature neutrophils in spleen and in cytoplasmic granules in peritoneal neutrophils. Detected in needle-shaped crystals present in the cytoplasm of bone marrow macrophages. Chitinase 3 like protein 4: Secreted. Cytoplasm. Note: Detected in the cytoplasm of keratinocytes.

  • ab211621 staining Chitinase 3 like protein 3 + Chitinase 3 like protein 4  in RAW264.7 cells. The cells were fixed with 100% methanol, permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab211621 at 1/100 dilution (pseudocolored in green). Nuclear DNA was labelled with DAPI (shown in blue). 

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).


    This product also gave a positive signal under the same testing conditions in RAW264.7 cells fixed with 4% formaldehyde.

  • Overlay histogram showing RAW264.7 cells stained with ab211621 (red line). The cells were fixed with 4% formaldehyde and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab211621, 1/1000 dilution) for 30 min at 22°C.        

    Isotype control antibody (black line) was rabbit IgG (monoclonal) Phycoerythrin (ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control. 

    Acquisition of >5,000 events were collected using a 50mW Yellow/Green laser (561nm) and 586/15 bandpass filter.               

    This antibody gave a positive signal in RAW264.7 cells fixed with 80% methanol (5 min), permeabilized with 0.1% PBS-Triton X-100 for 15 min used under the same conditions.
