Asked on Sep 10 2012
Thank you for your enquiry.
I can confirm that ab21640 and ab9519 are sold as whole antiseruma and ascites respectively. Unpurified antibodies, such as these sold as whole antiserum, ascites or tissue culture supernatant will not have a concentration stated on the datasheet. Antibody concentration is usually determined by protein assay, and serum / ascites / tissue culture supernatant will contain a lot of other proteins, which means the antibody quantification would not be accurate.
I can confirm that for whole antiserum, concentration of antibody is known to very between 1 - 10 mg/ml, while the Anti-Elastin antibody [BA-4] (ab9519) is estimated to be around 0.1-0.2 mg/mL.
I am sorry we are not able to provide an exact concentration on this occasion, but hope this information will be helpful to you. If you have any further questions, please do not hesitate to contact us.
