PAPPA / PAPP-A antibody was raised against purified human PAPP-A.
Specific for native human PAPP-A. Heat and SDS denatured PAPP-A is also recognized, but not acid-treated PAPP-A. The epitope is different from those of clones 6F172 and 6F174 and is located on the PAPP-A subunit of the heterotetramer. In sandwich ELISA the optimal combination was clone 6F174 as coating and biotinylated clone 6F173 as detection. This product detects only unreduced PAPP-A in Western Blot. It gives the strongest signal in Immunohistochemistry compared to clone 6F172 and clone 6F174.
Suitable for use in ELISA, Western Blot, and Immunohistochemistry. ELISA: 1:8000. In sandwich ELISA the optimal combination was clone 6F174 as coating and biotinylated clone 6F173 as detection. Western Blot: Detects only unreduced PAPP-A. Immunohistochemistry: Gives the strongest signal compared to clone 6F172 and clone 6F174.
