Alternate Antigen Name:
Deposit Date: 1/27/1998
Antigen Molecular Weight:
Depositor: Margolis, R.K. / Margolis, R.U.
Antigen Sequence:
Depositor Institution: New York University Medical Center / State University of New York
Antigen Species: rat
Depositor 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.
Host Species: mouse
Hybridoma Cells Available (Non-Profit): Yes
Confirmed Species Reactivity: Rat
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 RRID:AB_2173126
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. For immediate use, short term storage at 4°C up to two weeks is recommended. For long term storage, divide the solution into volumes of no less than 20 ul for freezing at -20°C or -80°C. The small volume aliquot should provide sufficient reagent for short term use. Freeze-thaw cycles should be avoided. For concentrate or bioreactor products, an equal volume of glycerol, a cryoprotectant, may be added prior to freezing.
Usage Recommendations
The optimal Ig concentration for an application varies by species and antibody affinity. For each product, the antibody titer must be optimized for every application by the end user laboratory. A good starting concentration for immunohistochemistry (IHC), immunofluorescence (IF), and immunocytochemistry (ICC) when using mouse Ig is 2-5 ug/ml. For western blots, the recommended concentration range of mouse Ig 0.2-0.5 ug/ml. In general, rabbit antibodies demonstrate greater affinity and are used at a magnitude lower Ig concentration for initial testing. The recommended concentrations for rabbit Ig are 0.2-0.5 ug/ml (IF, IHC and ICC) and 20-50 ng/ml (WB).
