Lab

Western blot - Anti-Bmi1 antibody [BMI1/2823] (AB269678)

Lanes 1- 4 : Merged signal (red and green). Green - ab269678 observed at 36 kDa. Red - Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) observed at 50 kDa.

ab269678 was shown to react with Bmi1 in wild-type MCF7 cells in western blot. Loss of signal was observed when knockout cell line ab262319 (knockout cell lysate ab256851) was used. Wild-type MCF7 and BMI1 knockout MCF7 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. ab269678 and Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker (ab52866) overnight at 4°C at a 2 μg/ml 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.

Protein Array - Anti-Bmi1 antibody [BMI1/2823] (AB269678)

Analysis of Protein Array containing more than 19,000 full-length human proteins using ab269678.

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 HuProt^TM 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 HuProt^TM 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 considered to 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.
