简介
Serum Amyloid A-1 Protein, a vital acute phase protein, primarily exists as a homohexamer composed of dimers of trimers.Although it can form amyloid fibrils after partial proteolysis, the native, undenatured form does not exhibit amyloid fibril formation in vitro.Serving as an apolipoprotein within the HDL complex, Serum Amyloid A-1 also shows affinity for heparin binding, highlighting its multifaceted role in biological processes.SAA1 Protein, Mouse (His) is the recombinant mouse-derived SAA1 protein, expressed by E.coli , with N-6*His labeled tag.

Protein Description
SAA1, or Serum Amyloid A1, is an acute-phase protein primarily synthesized by the liver in response to inflammation and tissue injury. It plays a crucial role in the body's innate immune response and has been implicated in various pathological conditions, including cardiovascular diseases, amyloidosis, and metabolic disorders. Research on SAA1 has gained considerable attention due to its potential as a biomarker for inflammation and disease prognosis. Recombinant SAA1 protein has emerged as a valuable tool in scientific studies, allowing researchers to investigate its biological functions, interactions with other molecules, and effects on immune responses in controlled settings. The ability to produce SAA1 recombinantly facilitates the exploration of its role in disease mechanisms and therapeutic applications, particularly in understanding how variations in SAA1 expression can influence inflammatory responses and contribute to chronic diseases. Furthermore, ongoing studies aim to elucidate the structural and functional aspects of this protein, advancing our knowledge of its pathophysiological implications and paving the way for potential interventions targeting SAA1-related pathways in various disease contexts. Overall, the investigation of SAA1 and its recombinant forms continues to hold promise for enhancing our understanding of immune responses and developing novel therapeutic strategies.
