Thank you for contacting us.
I have been in contact with the lab regarding this issue and have been informed that this product is not a purified IgG fraction as stated on the datasheet but is instead whole antiserum. This would explain the results which you have seen as the antiserum would contain other proteins as well. We are correcting this information on our datasheets presently.
We believe that this issue arose as we offer the IgG purified version of this product which has an internal designation number which is very similar to this product's number. The purified version of this anti-HRP is ab2115.
As this product is not as we have stated on our datasheet I may offer you replacement of this product should you wish. Please let me know if would like me to replace this product for you.
I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
