pH-sensitive probe fluorescent only under acidic conditions
Cat. No. 131 103CpH |
50 µg specific antibody, lyophilized. Affinity purified with the immunogen, fluorescence-labeled with CypHer5E.
CypHer5E® is a pH-sensitive dye, fluorescent only after antibody internalization at the acidic pH of the lumen of the synaptic vesicle. CypHer5E® can be detected with the filter sets for Cy5®. This product or portions thereof is manufactured under license from Carnegie Mellon University under U.S. Patent Application Number US 2006-0051758 and related patents.

Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye. |
Applications |
Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.', $event)" style="cursor: help;">IP: N/A 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.', $event)" style="cursor: help;">ICC: 1 : 100 up to 1 : 200 (see remarks) gallery 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.', $event)" style="cursor: help;">IHC: not tested yet 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.', $event)" style="cursor: help;">IHC-P: not tested yet |
Label | CypHer5E |
Immunogen | Synthetic peptide corresponding to residues near the carboxy terminus of rat VGAT (UniProt Id: O35458) |
Reactivity |
Reacts with: human (Q9H598), rat (O35458), mouse (O35633). Other species not tested yet. |
Specificity | K.O. validated |
Remarks |
ICC: This antibody is intended for direct labeling of recycling synaptic vesicles at inhibitory nerve terminals in living primary neuronal cultures. The pH sensitive dye regaines its fluorescence after the reacidification of the synaptic vesicle lumen. Further details see Martens et al. 2008. |
