Recombinant monoclonal antibody to IgA. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma H15A43.
UniProt Accession Number of Target Protein: P01876
Alternative Name(s) of Target: IGHA1; Immunoglobulin alpha; Immunoglobulin heavy constant alpha 1; Ig alpha-1 chain C region; Ig alpha-1 chain C region BUR; Ig alpha-1 chain C region TRO; HISA43; HISA-43
Immunogen: The original antibody was generated by immunizing BALB/c mice with human IgA myeloma protein or human parotid saliva.
Specificity: This antibody is a recombinant alternative to another anti-human IgA antibody HISA43. It is specific to heavy chain of human IgA and shows minimal cross-reaction with heavy chains of other immunoglobulins. It reacts with constant domain 3 (CD3) of both subclasses IgA1 and IgA2 of the human IgA heavy chain.
Application Notes: The specificity of this antibody to the CH3 domain of human IgA was determined using western blotting (PMID: 3093370). This recombinant antibody can be used to determine sIgA in a sample using ELISA (PMID:1872572). It can be used for the affinity purification of IgA from serum (PMID: 16395264).
