  • Application Supplier Note
    The original version of this antibody (mouse IgG1) was generated and used in ELISA, WB, IHC, SPR, and in vivo assays. ELISA analysis showed that the antibody reacts with type-III-repeats-containing FN fragments 7.EDB.8.9 and 7.EDB, and a Kd of 10 nM was measured in an SPR assay with 7.EDB.8.9 as the antigen. Western blot analysis showed that the epitope recognized by this antibody is located within the type III repeat 8 of FN. IHC analysis showed that this antibody strongly binds human-specific epitopes on repeat III8 of FN in neoplastic tissues. A murine urokinase-type plasminogen activator-conjugated mini-antibody version of the antibody was generated and utilized for in vivo tumor-targeting experiments in tumor-bearing mice expressing human B-FN using a radioiodinated mini-antibody. The distribution of the radioiodinated mini-antibody was assessed in tumor tissue and blood at different time points after injection, and the results showed rapid clearance from the bloodstream. Furthermore, the ratio of the percentage of injected dose per gram of tissue (%ID/g) in the tumor versus blood was higher than 10 in all cases, indicating high specificity for tumor tissue (Balza et al., 2009; PMID: 19479996). The reactivity of the scFv version of this antibody with wild-type and mutated fragments of the recombinant FN fragment EDB-III8 was examined via ELISA. It was found that the epitope of this antibody encompasses both E1329 on ED-B and D1385 on III8 and the simultaneous presence of both residues is required for the reaction; neither of the two residues alone is sufficient to ensure the interaction of this antibody with B-FN (Ventura et al., 2016; PMID: 26867013).

Figure 1. Western blot analysis of FN1 using anti-FN1 antibody (A00564-1). Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions. Lane 1: human placenta tissue lysates, Lane 2: human hepatocellular carcinoma tumor tissue (HCCT) lysates, Lane 3: human hepatocellular carcinoma paracancerous tissue (HCCP) lysates. After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-FN1 antigen affinity purified polyclonal antibody (Catalog # A00564-1) at 0.5 microg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for FN1 at approximately 220-400 kDa. The expected band size for FN1 is at 272 kDa.
