Depositors Notes: For immunocytochemistry use ascites at dilutions of 1:100-1:500. However, frequently grows as solid tumors, so yield of ascites may be very small. Hybridoma supernatant is most economical for use with immunoblots.
Predicted Species Reactivity:
Immunogen: PBS-soluble chondroitin sulfate proteoglycans from rat brain
Alternate Gene Names:
Alternate Antibody Name: protein tyrosine phosphatase - z/b
Additional Information: Protein tyrosine phosphatase that negatively regulates oligodendrocyte precursor proliferation in the embryonic spinal cord. Required for normal differentiation of the precursor cells into mature, fully myelinating oligodendrocytes. May play a role in protecting oligondendrocytes against apoptosis. May play a role in the establishment of contextual memory, probably via the dephosphorylation of proteins that are part of important signaling cascades
Recommended Applications: Immunohistochemistry, 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.
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).
All cell products contain the antimicrobial ProClin. See our FAQ section for additional information.
