Alternative NamesSAA1; Serum amyloid A-1 protein; SAA) [Cleaved into: Amyloid protein A; Amyloid fibril protein AA); Serum amyloid protein A(2-104); Serum amyloid protein A(3-104); Serum amyloid protein A(2-103); Serum amyloid protein A(2-102); Serum amyloid protein A(4-101)]

Function

Major acute phase protein.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Expressed by the liver; secreted in plasma (at protein level)
Disease Association: [Reactive, secondary amyloidosis is characterized by the extracellular accumulation in various tissues of the SAA1 protein. These deposits are highly insoluble and resistant to proteolysis; they disrupt tissue structure and compromise function] | [Elevated serum SAA1 protein levels may be associated with lung cancer]

Product Specifications

Recombinant Human Serum amyloid A-1 protein (SAA1) is a recombinant protein from Homo sapiens (Human), expressed in E.Coli, covering amino acids 19-122aa, with Tag-Free tag, molecular weight 11.7 kDa, purity >98% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.
