I need your help, in my blocking peptide experiment. Would you please answer to my questions: 1- How much antibody “ab5176” should I add to peptide “ab11477”? 2- Should I first aliquot both peptide and antibody? In what kind of buffer? 3- What kind of secondary antibody is suitable?

We generally suggest a 200fold molar excess of the peptide. This usually means ca 2ug peptide per 1 ug antibody. This can be increased to up to 500fold molar excess of the peptide if necessary. I suggest to use the same buffer that is used for the incubation steps with the antibody or just PBS Tween (0.1%) We also generally suggest to aliquot all antibodies and peptides to avoid contamination and to store them according to the instructions on the datasheet. A suitable secondary antibody for ab11477 is an anti rabbit antibody that is conjugated to HRP: Click here (or use the following: https://www.abcam.com/index.html?datasheet=6721).
