Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. 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.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
  5. Please refer to for technical protocols.

Cortactin is a protein which is represented by two structurally related isoforms of 80 kDa and 85 kDa. Sequence analysis of this protein reveals the presence of a carboxy-terminal SH3 domain, as well as six internal tandem repeats of a 37 amino acid sequence. It is able to bind to F-actin via this N-terminal repeat region, and colocalizes with actin in the cell. Cortactin was originally described as a protein that is tyrosine-phosphorylated in cells transformed by the src oncogene, in which it localizes to rosettes or podosomes. It has since been shown that other stimuli, such as bacterial invasion, treatment with growth factors, and integrin-mediated cell adhesion, are also capable of inducing phosphorylation of cortactin. Some additional evidence indicates that cortactin may actually be a substrate of syk, with src acting as an upstream signaling molecule.

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.
