(anti-Human and others as indicated)

RDI Divison of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

catalog#   RDI-TRK4P41- clone#     example: RDI-TRK4P41-5H9    (for clone 5H9)

Monoclonal antibody: 5H9, 10E1, 10E2, 4G11, 10A5, 3C8, 10H9, 18A10, 11E4

Hybridoma clones, producing MAbs, have been derived from hybridization of SP2/0 myeloma cells with spleen cells of Balb/c mice immunized with purified human PAPP-A antigen.

Specificity: Human PAPP-A antigen purified from placental blood (heterotetrameric complex, consisting of two PAPP-A subunits and two pro-MBP subunits) Clone 11E4 is specific to proMBP subunit.

Mouse isotype: IgG2b for MAb 5H9, 10E1 and 10E2

                         IgG2a for clones 4G11, 10A5, 3C8, 10H9 and 18A10

Application: Detection of human PAPP-A antigen in immunoassay.

Recommended pairs (coating - conjugate) :  for the detection of PAPP-A in blood of AMI patients and patients with unstable angina (capture - detection): 4G11 – 3C8, 4G11 – 10H9, 10E2 – 10E1

Best pairs for the detection of PAPP-A in pregnancy serum (capture – detection): 4G11 – 3C8, 4G11 – 10H9, 10A5 – 3C8, 10E2 – 10E1, 10E2 – 5H9, 5H9 – 10E2

     MAbs 4G11, 10A5, 18A10  (best) and 10E1 recognize PAPP-A subunit in the heterotetrameric complex in Western Blotting. MAb 11E4 recognizes proMBP subunit in Western Blotting

Purification: All MAbs are purified by chromatography on protein A Sepharose. Clone 10E2 is additionally purified by gel-filtration. Purity of all MAbs is tested by electrophoresis.

Presentation: Each vial contains antibodies in PBS, pH 7,4, containing 0,1% of sodium azide as preservative. Store at + 4 °C.

Material safety note: This product is sold as an antibody preparation for research purpose only. Standard Laboratory Practices should be followed when handling this material. Contains sodium azide (0,1%) as preservative. Although the amount of sodium azide is very small appropriate care must be taken when handling this product.
