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. |

IHC-P |
Use at an assay dependent concentration.

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. -

Performed under reducing conditions.ab31850 was shown to react with SPAST in wild-type HEK293T cells in Western blot with loss of signal observed in SPAST knockout cell line ab267238 (SPAST knockout cell lysate ab258698). Wild-type HEK293T and SPAST knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab31850 overnight at 4 °C at a 1/500 dilution. Blots were incubated with goat anti-rabbit HRP secondary antibodies at 0.2μg/mL before imaging.

Observed band size: 55 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-Spastin antibody [Sp 3G11/1] staining at 1/500 dilution, shown in green; Rabbit Anti-GAPDH antibody [EPR16891] (ab181602) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab31850 was shown to bind specifically to Spastin. A band was observed at 55 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in SPAST knockout cell line ab267238 (knockout cell lysate ab258698). To generate this image, wild-type and SPAST knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) at 1/20000 dilution.

Anti-Spastin antibody [Sp 3G11/1] (ab31850) at 1/500 dilution + rat brain synaptosome
Observed band size: 52 kDa why is the actual band size different from the predicted?
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. -
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.
