Spinophilin antibody - 399 003 K.O.

Spinophilin is enriched at dendritic spines
Rabbit polyclonal purified antibody
Cat. No.: 399 003
Amount: 50 µg
Price: $375.00
Cat. No. 399 003 50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin was added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.
Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications
 
WB: 1 : 1000 (AP staining) gallery  
IP: not tested yet
ICC: 1 : 500 up to 1 : 1000 gallery  
IHC: 1 : 500 up to 1 : 1000 gallery  
IHC-P: 1 : 500 gallery  
DNA-PAINT: yes (see remarks)

Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

In antibody-based DNA-PAINT (Point Accumulation in Nanoscale Topography), a short oligomeric docking strand is coupled to a specific antibody. The transient association of the fluorophore to the antibody is mediated by the pairing of a short fluorescently labeled complementary imager DNA strand. DNA-PAINT allows super-resolution imaging and the imaging of a huge number of antibodies on the same biological sample in a single multiplex experiment. For additional experimental details refer to the Remarks section.

Immunogen Synthetic peptide corresponding to AA 290 to 302 from rat Spinophilin (UniProt Id: O35274)
Reactivity Reacts with: rat (O35274), mouse (Q6R891).
Other species not tested yet.

Remarks

Background
Spinophilin, also known as Neurabin II, is a scaffolding protein enriched in neuronal dendritic spines. It is involved in the targeted loacalization of protein phosphatase-1 (PP1), critical for dopaminergic modulation of glutamate neurotransmission.
More recently it has also been identified as a tumor suppressor. Loss of its function induces a proliferative response by increasing retinoblastoma protein (pRb) phosphorylation.
