(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Mab to Synaptopodin

cat#RDI-PRO65194   $375.00

Clone                               G1D4

Category                           Mouse monoclonal

Immunoglobulin Class       IgG1

Form/Purification              Cell culture supernatant

Antigen                               isolated rat kidney glomeruli

Clinical Application/Specificity The antibody recognizes differentiated podocytes(glomerular visceral epithelial cells) in vivo and in vitro. Weaker additional reaction with arterial endothelial cells. 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.

Polypeptide Reacting: Reacts specifically with synaptopodin, a prolin-rich actin binding protein with 2 binding sites for actin. Synaptopodin represents a new class of actin-binding proteins which has 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,pI9.27. In SDS-PAGE the antigen appears as 100kd polypeptide in brain and 110kD polypeptide in kidney(the difference might be attributed to posttranslational modifications). In Western blot analysis the antibody also reacts with a 44kd degradation fragment of synaptopodin.

Antigen Recognizied: Human, bovine, rat, mouse, guinea pig, gerbil (negative with rabbit, frog chicken)
