Thank you for getting back to me with those details, it was very interesting. Unfortunately given that the source of the antisera have not been able to provide me with further details as to the synthesis of the immunising peptides it is difficult for me to comment on whether they have been raised against a correctly folded immunogen. If this was indeed the case then one might speculate that these antibodies only recognise the synthetic peptide and not the native form of the protein. However, checking back to past orders and this antibody is relatively popular and we have not received any complaints as such. I can but speculate that the absence of western or dot blot as applications on the datasheets is a reflection that these antibodies do not recognise their epitopes when immobilised on a membrane.

Thank you for your enquiry. Further to correspondence with the source of this antiserum I have been informed that the antiserum was raised against tricycle human ß-Defensin 2 antigen. Unfortunately they could not provide details of whether the antisera had been tested against the native protein or your protein standards. I have therefore not been able to find evidence that these sera have been tested against the native form of this protein. I would definitely be interested to know how these sera performed against the denatured forms of your standards.

Thank you for contacting me. Unfortunately I have not been able to obtain a satisfactory answer from the source of this antiserum as yet. I will be in touch as soon as I know more details about the synthesis of the immunising peptides. I appreciate your patience.

Thank you for your enquiry and your patience. The members of the defensin family are classified based on the position of the three íntramolecular disulfide bridges between cystein residues. They are classified as alpha- and beta-defensins. We have monoclonal antibodies specific for beta-defensin 1 and beta-defensin 2. They were generated against the respective synthetic peptides (with correct disulfide bridges). A sequence alignment of the two sequences gives no similarity beyond the position of the cystein residues. It is not likely that the antibodies cross react. However, this has not been tested experimentally. We hope you will find this information useful.
