The antibody reacts specifically with Synaptopodin. It recognizes 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.
Cross-Reactivity (Details)
Species reactivity (tested):Human, Bovine, Rat, Mouse, Guinea Pig and Gerbil. Negative with Rabbit, Frog and Chicken.
Immunofluorescence. Immunohistochemistry on Frozen SectionsImmunohistochemistry on Paraffin Embedded Tissue: 1/5-1/10 for 1 h at RT (Aftermicrowave treatment). Immunoblotting (Western): 0.1-0.5 μg/mL. The antibody also reacts with a 44 kD degradation fragment of Synaptopodin. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

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 73.7 kD and pI of 9.38 (calculated from sequence data), in mouse the corresponding data are 74 kD, pI 9.27. In SDS-PAGE the antigen appears as 100 kD polypeptide in brain and 110 kD polypeptide in kidney (the difference might be attributed to posttranslational modifications).Synonyms: KIAA1029
