• Product name
  • Description
    Goat polyclonal to Urokinase
  • Specificity
    The antibody is highly specific for urokinase, no crossreactions were found with other serine proteases (tissue plasminogen activator, plasmin, trypsin, chymotrypsin, elastase, thrombin).
  • Tested applications
    Suitable for: Dot blot, ICC/IF, IHC-Fr, IHC-P, ELISA, WB, RIAmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Extensively purified HMW-tcuPA and LMW-scuPA (mixture 50/50), isolated from urine (Human).

  • Positive control
    • This antibody gave a positive result when used in the following methanol fixed cell lines: DU145.
  • General notes

    ab24122 binds to human HMW-scuPA (54 kDa), HMW-tsuPA (52 kDa) and LMW-scuPA (33 kDa) with high apparent affinity (Kd= 0.1 nM) completely inhibiting the ability of urokinase to activate plasminogen. Urokinase reaction with synthetic substrate S2444 is also inhibited. Human whole plasma or plasma proteins do not interfere with its binding to urokinase.



Our Abpromise guarantee covers the use of ab24122 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Function
    Specifically cleave the zymogen plasminogen to form the active enzyme plasmin.
  • Tissue specificity
    Expressed in the prostate gland and prostate cancers.
  • Sequence similarities
    Belongs to the peptidase S1 family.
    Contains 1 EGF-like domain.
    Contains 1 kringle domain.
    Contains 1 peptidase S1 domain.
  • Post-translational
    Phosphorylation of Ser-158 and Ser-323 abolishes proadhesive ability but does not interfere with receptor binding.

Anti-Urokinase antibody images

  • ICC/IF image of ab24122 stained DU145 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA /0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab24122 at 10µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 donkey anti- goat (ab96931) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
