This data was developed using the same antibody clone in a different buffer formulation (ab218400).

  Lanes 1- 2: Merged signal (red and green). Green - ab218400 observed at 20 kDa. Red - Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) observed at 50 kDa.

 ab218400 was shown to react with Ferritin Light Chain in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265534 (knockout cell lysate ab256927) was used. Wild-type HeLa and FTL knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab218400 and Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye^®800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye^®680RD) preadsorbed (ab216777) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

This data was produced with ab218400, the same antibody in a different formulation with BSA and Azide.
ab218400 was tested in protein array against over 19000 different full-length human proteins.
Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.
A MAb is specific to its intended target if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.

This data was developed using the same antibody clone in a different buffer formulation (ab218400).

Lanes 1 - 4: Merged signal (red and green). Green - ab218400 observed at 20 kDa. Red - loading control, ab181602, observed at 37 kDa.

ab218400 was shown to recognize Ferritin Light Chain in wild-type HAP1 cells as signal was lost at the expected MW in FTL (Ferritin Light Chain) knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and FTL (Ferritin Light Chain) knockout samples were subjected to SDS-PAGE. Ab218400 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye^® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye^® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
