Technical Data
Cortactin (p80,85)
Cortactin is present as a p80 and p85kD protein in many cell types. The protein was first identified as being a major substrate of the tyrosine kinase pp60SRC. The main structural feature of the protein is that at the N-terminus there are five and a half 37-amino acid repeats, these appear to be responsible for the actin-binding. This repeat region occupies about a third of the protein. The repeat region is followed by a helical region and then a proline rich region and finally a SH3 domain.

Suitable for use in Western Blot, Immunoprecipation and Immunocytochemistry. Other applications not tested.

Recommended Dilutions:
Western Blot: 0.5-2ug/ml detects Cortactin (p80/85) in mouse 3T3/A31 cell lysates. Detects Cortactin in chicken fibroblast src-transformed cell lysate. 3T3/A31 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with C7901-80. Proteins were visualized using an IgG (HRP) Gt x Mo and a chemiluminescence detection system.
Immunoprecipitation: Use 5ug for ~500ug of cell lysate.
Immunocytochemistry: 10ug/ml
Optimal dilutions to be determined by the researcher.

Sp2/0 myeloma x AJ mouse splenocytes

Included Positive Antigen Control:
F4209: 3T3/A31 cell lysate. Add 2.5ul 2-mercaptoethanol/100ul of lysate. Boil for 5 minutes to reduce the preparation. Load 20ug of reduced lysate per lane.
Note: PC-12 cell lysate, HeLa whole cell lysate or A431 whole cell lysate can also be used as a positive control.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
