Product Specific Information
Each blood donation used for interferon production tested negative for: HBsAg, HIV I-II, HCV and VDRL.
After receipt, this product should be kept at 4°C while lyophilized and at -70°C after reconstitution in sterile distilled water for retention of full activity. After reconstitution store at -70°C in aliquots. When thawing, the contents of the tube should be apportioned in separate tubes so that freezing and thawing is kept to a minimum. Further dilute only in buffers containing protein such as 0.1% bovine serum albumin (BSA).
Target Information
IFN alpha (Interferon alpha) is a Type I interferon belonging to a family of structurally related, species-specific proteins exclusive to vertebrates. The interaction of IFN-alpha with its receptor component result in the activation of a number of signaling pathways which are mainly involved in innate immune response against viral infection. In humans, the gene for IFN alpha is located on on chromosome 9. The type I interferons consist of 14 different alpha isoforms (subtypes with slightly different specificities), and single beta, omega, epsilon and kappa isoforms. Homologous molecules are found in many species, including rats and mice (and most mammals), and have been identified in birds, reptiles and fish species. IFN alpha is produced primarily by plasmacytoid dendritic cells, is a potent component of the anti-viral innate immune response and modulates adaptive immunity. Diseases associated with the dysfunction of IFN alpha include Hepatitis C and Hepatitis.
