Mouse monoclonal purified IgG

Cat. No.: 131 011C2

Amount: 100 µg

Price: $475.00

Cat. No. 131 011C2	100 µg purified IgG, lyophilized, fluorescence-labeled with Cyanine 2. Fluorescence labeled antibodies conjugated to (Sulfo-)Cyanine dyes are well suited for standard epi-fluorescence setups and confocal microscopy. Cyanine 2: λ_ex 492 nm / λ_em 508 nm Sulfo-Cyanine 3: λ_ex 554 nm / λ_em 568 nm Sulfo-Cyanine 5: λ_ex 649 nm / λ_em 667 nm (Sulfo-)Cyanine 5 dyes are well suited for STORM high resolution microscopy. Sulfo-Cyanines are highly water soluble and allow a higher labeling degree and consequently brighter conjugates. Albumin was added for stabilization. For reconstitution add 100 µl H₂O to get a 1mg/ml solution in TBS. 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 up to 1 : 1000 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.

Background

The vesicular GABA transporter VGAT is responsible for uptake and storage of GABA and glycine by synaptic vesicles in the central nervous system. For this reason it is frequently referred to as the vesicular inhibitory aminoacid transporter VIAAT. It is different from the plasma membrane transporters in that it is driven by a proton electrochemical gradient across the vesicle membrane. So far, only one isoform is known. VGAT is currently the best marker for inhibitory nerve terminals.
