CD20 Monoclonal Antibody AE00203

Confocal microscopy of Raji stained with CD20 Mouse Monoclonal Antibody AE00203 at 1-2ug/ml (1h at ambient temp). Detection by CF488 (green) for the antibody and redDot (red) for nuclear staining.

Formaldehyde-fixed, paraffin-embedded human tonsil stained with CD20 Mouse Monoclonal Antibody AE00203 at 0.5-1ug/ml for 30 minutes at RT. Epitope retrieval: Boiling at pH6 for 10-20 min followed by 20 min cooling. DAB staining by HRP polymer.

Western Blot of a Raji lysate (30ug) stained with CD20 Mouse Monoclonal Antibody AE00203 at 1ug/ml (1h at ambient temp). ECL staining by HRP.

Cross-reactivity assessment of CD20 Mouse Monoclonal Antibody AE00203 (1ug/ml) on CDI’s Protein Array containing more than 19,000 full-length human proteins.
The Z-score represents the strength of a signal that an antibody (through a fluorophore-tagged secondary reagent) produces when binding to a particular protein on the array. Z-scores are in units of standard deviations (SD’s) above the mean value of all signals generated on that array. When Z-scores are arranged in descending order, the difference between two successive values will be the S-score for the first. Thus, the S-score represents the relative specificity of the antibody to its intended target. An antibody is considered specific to its intended target, when it has an S-score of at least 2.5. For example, if an antibody binds to intended protein X with a Z-score of 43 and to the cross-reacting protein Y with a next Z-score of 14, then the S-score for the antibody to intended target X equals 29 (43-14).

Integrity of the purified antibody AE00203 under non-reduced and reduced conditions, showing intact IgG at around 150kDa (NR) and intact heavy and light chains at 50kDa and 25kDa resp. (R). Note different sizes due to PTMs.
