| Popis: | In this work, polyclonal antibodies anti-human Factor IX were produced in New Zealand rabbits by immunization with commercial pure human FIX (hFIX) (Octanyne®, Octapharma, USA). The serum containing immunoglobulins anti-hFIX was useful to detect hFIX antigen in human plasma fractions submitted to anionic exchange chromatographic process and with a large yield. Immunoassays (ELISA) using bovine serum albumin, trypsin and peptides generated by cleavage assays with trypsin as digestion enzyme was performed and revealed adequate specificity of the polyclonal antibodies produced.Neste trabalho foram produzidos anticorpos policlonais anti-fator IX humano em coelhos New Zealand imunizados com FIX humano (hFIX) comercial puro (Octanyne®, Octapharma, EUA). O soro contendo as imunoglobulinas anti-hFIX foi útil para a detecção do antígeno hFIX em frações do plasma humano submetido a cromatografia de troca iônica. Imunoensaios (ELISA) usando soro-albumina bovina, tripsina e peptídeos gerados por ensaios de clivagem com tripsina com enzima de digestão foram realizados e revelaram especificidade adequada dos anticorpos policlonais produzidos. |
