  • ChIP of ΔNp73 binding with SBE. The relative amount of ΔNp73 associated DNA as pulled down with an antibody directed against HA, is represented as a fold enrichment compared to pull-down with IgG (background, ab18413). Gene enrichment was quantified by qPCR using primers specific for the promoter regions of A) PAI-1, B) Col1a1 and C) p21WAF within the SBEs. Primers specific for PTEN (D) were used as a positive control. Pulldown antibody is shown on the x-axis, with y-axis showing fold enrichment ± SEM. * represents p-value>0.05.

Thank you for your reply.

They are the same antibody (same clone), just that ab18449 has been screened for low endotoxin levels for use with cell culture.

I hope this information helps. Please contact us with any other questions.

Thank you for contacting us.

The anti-IL6 antibody ab9324 is a mouse monoclonal IgG2a. Therefore, you will need to use a mouse monoclonal IgG2a isotype control.

Therefore, you should use the mouse control IgG2a ab18413 and NOT the rabbit IgG ab37415.
