| Application notes | Humanized Recombinant Anti-HER2 Fab fragment Antibody has been tested for use in Flow Cytometry, Western Blot, and ELISA. This antibody recognizes structured HER2 and will work in western blot when the protein has not been denatured with DTT or bMe. Although not tested, this antibody could be useful in in IHC and in in-vivo and other cellular assays. Specific conditions for reactivity should be optimized by the end user. |
| Expiration Date | 12 months from date of receipt. |
ELISA results show the sensitivity of Humanized Recombinant Anti-human HER2 Fab fragment Antibody tested against purified HER2 protein. Each well was coated in duplicate with 1.0 µg of HER2. The starting dilution of antibody was 5.0 µg/ml.
Flow Cytometry of Humanized Recombinant Anti-human HER2 Fab fragment Antibody. Primary Antibody: Recombinant Anti-HER2 Fab fragment (red line) recognizes HER2 on SK-OV-3 cells while using Anti-human kappa FITC secondary antibody at 0.2 µl with a 56.8% positive cells. Controls used: (black line) no primary antibody, no secondary antibody, 0.6%; (green line) no primary antibody, Anti-human kappa FITC secondary antibody at 0.2 µl, 1.0%.
