General description

Monoclonal Anti-Alpha-1-Antitrypsin (AAT) (mouse IgG2b isotype) is derived from the hybridoma 1C2 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a human AAT recombinant protein. Alpha-1-Antitrypsin (AAT), also named SERPINA1 (serine proteinase inhibitor, clade a, member 1), is a member of the protease inhibitor (serpin) family. It is encoded by the gene SERPINA1. AAT is a glycoprotein synthesized mainly in the liver and secreted to the bloodstream. This gene consists of four coding exons (II, III, IV, and V) and three untranslated exons (Ia, Ib, and Ic) in the 5′ region and six introns.

Immunogen

human AAT recombinant protein

Application

Monoclonal Anti-Alpha-1-Antitrypsin (AAT) antibody has been used in immunoblotting and microarray.

Biochem/physiol Actions

Serpin peptidase inhibitor clade a member 1 (SerpinA1) is considered as a biomarker for the progression of cutaneous squamous cell carcinoma. It serves as an effective inhibitor of neutrophil elastase. AAT is a major serine protease inhibitor whose targets include elastase, plasmin, thrombin, trypsin, chymotrypsin, and plasminogen activator. Through circulation AAT reaches the lungs where it blocks the effects of neutrophil elastase. Defects in this gene can cause emphysema or liver disease.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

During biosynthesis, proteins can begin folding co-translationally to acquire their biologically-active structures. Folding, however, is an imperfect process and in many cases misfolding results in disease. Less is understood of how misfolding begins during biosynthesis. The human protein, alpha-1-antitrypsin (AAT)
