    Alomone Labs synaptotagmin
    WT1 -expressing neurons terminate in close proximity to populations of commissurally projecting interneurons. A , A 20-μm-thick section of a spinal cord 46 h after PRV-152 injection into the GS muscle on the left side and stained with antibodies to GFP (green) and WT1 (blue). At this time point, no WT1 -expressing neurons on either side of the spinal cord have taken up the tracer. Contralateral region containing WT1 -expressing cells (dashed box) is expanded to the right. B , To identify presumptive synapses on genetically defined interneuronal subtypes, we inspected the <t>synaptotagmin</t> + “halo” (indicated by white arrows) surrounding each labeled nuclei for WT1 + /synaptotagmin + terminals. C–F , The 20-μm-thick sections cut from a P0 WT1 CreER ROSA26 tdTomato spinal cord and stained with antibodies to tdTomato (red), the synaptic marker synatotagmin (blue), as well as (green) a nuclear marker of V2a cells ( Chx10 -, C ), V1 cells ( En1 -, D ), V0 V cells ( Evx1 -, E ), or DMRT3 -expressing dI6 cells ( F ). WT1 -expressing terminals (tdTomato + /synaptotagmin + processes) were rare or absent nearby Chx10 - or En1 -expressing cells but were commonly seen in close proximity to Evx1 + and DMRT3 + neurons. C , D , Dashed boxes are expanded to the right. E , F , Arrow in the low-magnification image indicates the specific WT1 cell of interest in the panel to the right. In magnified images, arrows indicate presumptive WT1 + axon terminals. Double labeling of these processes is confirmed in orthogonal views to the right of E , F . Scale bars: Low-magnification images, 100 μm; High-magnification images: A , C , D , 20 μm; B , E , F , 5 μm.

A, RT-PCR results of the Ca 2+ -dependent synaptotagmin family in brain microsome and parotid acinar cells from mice and rats. Lane numbers indicate synaptotagmin isoforms. B, size of PCR products encoding synaptotagmin isoforms and summary of results. Note that rat parotid acinar cells express synaptotagmin isoforms 1, 3, 4, and 7. Each result is the representative of five to eight different experiments. C, Western blotting of synaptotagmin 1 in brain, parotid, submandibular, and pancreatic acinar cells from mice and rats.

    Specific silencing of SNAP-25 by RNA interference . A) Immunoblots were done to assess the levels of SNAP-25, SNAP-23, synaptotagmin I, syntaxin 1A, tyrosine hydroxylase and β-actin in wild type PC12 cells, SNAP-25 knockdown cells and in control transfected cells (PC12 cells stably transfected with pG418-shRNA lacking an shRNA insert). Equal amounts of protein were loaded per lane. B) The SNAP-25 phenotype is maintained for at least 10 weeks in culture in both the parent PC12 cell line and the SNAP-25 knockdown cell line. C) Human and zebrafish SNAP-25 mRNAs are resistant to RNA interference. The specificity of the SNAP-25 shRNA was demonstrated by transiently transfecting SNAP-25 knockdown cells with plasmids designed to express SNAP-25 cDNA of rat, human, or zebrafish origin. The 19 nucleotide region of rat SNAP-25 mRNA which is targeted by the SNAP-25 shRNA differs from human SNAP-25 RNA at only 2 positions and from zebrafish SNAP-25 mRNA in 4 positions. The immunoblot shows that expression of rat SNAP-25 was silenced in the SNAP-25 knockdown cells, but human and zebrafish SNAP-25 were expressed. All three SNAP-25 cDNAs appeared to be expressed in the control transfected cells in that there was more SNAP-25 in the control transfected cells than in untransfected PC12 cells. The immunoblot was stripped and reprobed for β-actin to demonstrate approximately equal amounts of protein in each sample. D) SNAP-25 mRNA is reduced in SNAP-25 knockdown cells. RT-PCR was carried out with RNA isolated from wild type PC12 cells, SNAP-25 knockdown cells and in control transfected cells. SNAP-25 mRNA was easily detected in wild type and control transfected PC12 cells, but no SNAP-25 mRNA was detected in the SNAP-25 knockdown cells in this PCR experiments. However, if more of the reverse-transcription product was used for the PCR or if more cycles were done in the PCR reaction, some SNAP-25 mRNA was detectable in the SNAP-25 knockdown cells.
