应用 Ab评论 说明
WB 1/500. Detects a band of approximately 52 kDa. There are two splice isoforms of spastin, one without exon4 and two alternative ATG start sites, which may determine the localisation of the translate protein. 52kDa is the major band.
ELISA Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration. PubMed: 21757506
ICC/IF Use at an assay dependent concentration. PubMed: 21757506

    Spastin is thought have a role in microtubule dynamics through its function as a microtubule severing protein. It is localised to the centrosome of neuronal cells but is not found in glial cells. Mutation in the ATPase binding domain of spastin causes hereditary spastic paraplegias (HSP), a large group of clinically similar disorders. Mutant forms of spastin are generally found throughout the cytoplasm rather then within the nucleus.

    Observed band size : 52 kDa (why is the actual band size different from the predicted?)
  • IHC image of Spastin staining in Human lung adenocarcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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 ab31850, 10µg/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.

Thank you for your response.

I would expect ab31850 to give clearer results in WB, even once the many isoforms are taken into consideration. I would be happy to offer you a free of charge replacement, credit, or refund for this antibody as we...

Thank you for your reply.

For the Spastin antibody ab31850, could you please provide an image of your blot or let me know what size bands you are observing? Spastin has several known isoforms that could account for multiple bands between 54-6...

First of all I would like to apologise for the delay in getting back to you. I really appreciate your patience and comprehension.

I contacted my lab colleagues and unfortunately there isn’t any information available about the epitope re...
