Synaptopodin (SYNPO, KIAA1029)
Description:
Synaptopodin, a prolin-rich actin-binding protein with 2 binding sites for actin, represents a new class of actin-binding proteins which has first been localized in podocytes and a subset of telencephalic postsynaptic densities. In human tissue synaptopodin has a molecular weight of 73.7kD and pI of 9.38 (calculated from sequence data); in mouse the corresponding data are 74kD, pI 9.27. In SDS-PAGE the antigen appears as 100kD polypeptide in brain and 110kD polypeptide in kidney (the difference might be attributed to posttranslational modifications).

Applications:
Suitable for use in Immunofluorescence, Western Blot and Immunohistochemistry. Other applications have not been tested.

Recommended Dilutions:
Immunohistochemistry (Frozen): Neat
Immunohistochemistry (Paraffin): Requires microwave treatment prior to incubation.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Form
Supplied as a liquid, 0.01% sodium azide.
Specificity:
Recognizes rat synaptopodn. Reacts with differentiated podocytes (glomerular visceral epithelial cells) in vivo and in vitro (weaker additional reaction with arterial endothelial cells), co-localization with alpha-actinin. Does not react with parietal cells. Reacts with a subset of exclusively telencephalic synapses. Differentiation- dependent expression during postnatal maturation of rat brain. Differentiation-dependent expression in cultured hippocampal neurons. Species Crossreactivity: human, bovine, mouse, guinea pig and gerbil. Does not react with rabbit, frog, or chicken.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
