Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Receptor-like protein tyrosine phosphatases (RPTPs) represent an important  pathway for signal transduction via modification of protein tyrosine phosphorylation status. RPTPα is widely expressed and is particularly abundant in brain. Structurally, it is typical of RPTPs in that it has an intracellular region containing two tandem catalytic domains linked to a transmembrane and an extracellular region. However, unlike many RPTPs, the extracellular region of RPTPα is small (123 residues) and lacks any obvious structural motifs, though the protein is known to be heavily glycosylated. Both catalytic domains of RPTPα have intrinsic in vitro activity, but their exact roles in vivo remain uncertain. It has been postulated that due to their transmembrane nature, RPTPs are initiators for a cascade of intracellular signaling events, much like receptor tyrosine kinases.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
