Our Abpromise guarantee covers the use of ab72505 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use at an assay dependent concentration. PubMed: 20890278|
|ICC||1/100 - 1/500.
Formaldehyde fixation with Triton-X 100 permeabilization is recommended.
|WB||1/2000 - 1/10000. Detects a band of approximately 220 kDa (predicted molecular weight: 176 kDa).|
|IP||Use at 2-5 µg/mg of lysate.|
|IHC-P||Use a concentration of 0.5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
RelevanceCEP170, centrosomal protein 170kDa, plays a role in microtubule organization. During interphase, the encoded protein localizes to the sub-distal appendages of mature centrioles, which are microtubule-based structures thought to help organize centrosomes. During mitosis, the protein associates with spindle microtubules near the centrosomes.
Cellular localizationCentrosome, centriole. Cytoplasm, cytoskeleton. Associated with the mature mother centriole. Associated with spindle microtubules during mitosis.

Immunocytochemistry/Immunofluorescence analysis of NBF-fixed asynchronous HeLa cells labelling CEP170 with ab72505 at 1/200. A red-fluorescent goat anti-rabbit IgG (1/100) was used as the secondary antibody.
IHC image of CEP170 staining in Human Testis formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab72505, 0.5 µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
All lanes : Anti-CEP170 antibody (ab72505) at 0.04 µg/ml
Lane 1 : HeLa whole cell lysate at 50 µg
Lane 2 : HeLa whole cell lysate at 15 µg
Lane 3 : HeLa whole cell lysate at 5 µg
Predicted band size: 176 kDa
Observed band size: 220 kDa why is the actual band size different from the predicted?
Additional bands at: 65 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 30 seconds
