Rabbit polyclonal purified antibody

Cat. No.: 105 223CpH

Amount: 50 µg

Price: $495.00

Cat. No. 105 223CpH	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^®. CypHer5E^®: λ_ex 647 nm / λ_em 667 nm 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.

Purchase of reagents related to the CypHer technology from Synaptic Systems GmbH provides a license for non-profit and in-house research use only. Any application of above mentioned technology for commercial purpose requires a separate license from GE-Healthcare Bio-Science Corp., 800 Centennial Avenue, Piscataway, NJ 08855-1327, USA. Albumin was added for stabilization. For reconstitution add 50 µl H₂O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives. Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.
Applications	WB: N/A IP: N/A ICC: 1 : 100 (see remarks) gallery IHC: not tested yet IHC-P: not tested yet Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section. Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section. 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. 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. 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.
Label	CypHer5E
Immunogen	Synthetic peptide corresponding to AA 1 to 11 from mouse Synaptotagmin2 (UniProt Id: P46097)
Reactivity	Reacts with: rat (P29101), mouse (P46097). Other species not tested yet.
Remarks	ICC: This antibody can only be used for labeling of recycling synaptic vesicles in living neurons. It is not recommended for the staining of fixed cells. The pH sensitive dye regaines its fluorescence after the reacidification of the synaptic vesicle lumen.

Background

Synaptotagmin2 is an integral membrane glycoprotein of neuronal synaptic vesicles. It is very similar to synaptotagmin1 but shows a partly complementary expression pattern in the CNS. Synaptotagmin2 lacks a CAMK II/PKC phosphorylation site which is present in synaptotagmin1.
Recently synaptotagmin2 has been shown to be an alternative Ca²⁺ sensor for fast secretion.
