Bacterially expressed purified protein corresponding to the entire extracellular domain of rat TrkA receptor.
TrkA has an apparent molecular weight 140kD and is a high affinity nerve growth factor (NGF). Applications: Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications have not been tested. Recommended Dilutions: Immunohistochemistry (Paraffin): Requires HIER using sodium citrate buffer pH 6.0 prior to staining. Immunocytochemistry: Positive staining for TrkA in PC-12 cells fixed with 4% paraformaldehyde. Optimal dilutions to be determined by the researcher. Included Positive Antigen Control: A0001-50: Non-stimulated A431 cell lysate. Add 2.5ul of 2-mercaptoethanol/100ul of lysate and boil for 5 minutes to reduce the preparation. Load 20ug of reduced lysate per lane for minigels. Storage and Stability: Store product at 4C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20C. Aliquots are stable at -20C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
