Détail du antigène

Antigène: IFN alpha 1b

Autre désignation: Interferon-Alpha1b (IFN-Alpha1b)

Synonymes: IFL Protein, IFN Protein, IFN-ALPHA Protein, IFN-alphaD Protein, IFNA13 Protein, IFNA@ Protein, interferon alpha 1 Protein, IFNA1 Protein

Sujet: At least 23 different variants of IFN-alpha are known. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end. Synonym: Interferon-alpha1b (IFN-alpha1b), Human. Formulation: Lyophilized from a 0.2µm filtered solution in PBS, pH 7.4, containing 4% mannitol and 1% HSA.

Poids moléculaire: Approximately 19.5 kDa, a single non-glycosylated polypeptide chain containing 167 amino acids.
