Additional Information: This antibody recognizes all known CSP isoforms. CSP is associated with the cytoplasmic surface of synaptic vesicles and is often used as a synaptic vesicle marker. It labels all synapses. See [PMID: 9799436 and 8310297] for a comparison between DCSP-1, DCSP-2 and DCSP3 mAbs. CSP is also known as DnaJ homolog subfamily C member 5 homolog.
Recommended Applications: Immunofluorescence, Immunohistochemistry, Immunoprecipitation, Western Blot

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable. To ensure retention of antibody activity, we recommend aliquotting the product into two parts: 1) a volume of antibody stored at 4°C to be used within two weeks. 2) the remaining product diluted with an equal volume of molecular grade glycerol and stored at -20°C.
Usage Recommendations
While optimal Ig concentration for an application will vary, a good starting concentration for immunohistochemistry (IHC), immunofluorescence(IF) and staining is 2-5 µg/ml. For Western blots, the concentration is decreased by one order of magnitude (that is, 0.2-0.5 µg/ml).
