Recombinant Human Apolipoprotein-Serum Amyloid A1 (rHuApo-SAA1)

Serum amyloid A-1 protein which belongs to the SAA family is encoded by the SAA1 gene in humans. It is expressed by the liver and secreted in plasma. Serum amyloid A-1 is the major acute phase reactant and apolipoprotein of the HDL complex.

Elevated serum SAA1 protein levels may be associated with lung cancer. The level of Apo-SAA1, normally 1-5 μg/ml in plasma, increases 500-1000 fold within 24 hours of an inflammatory stimulus and, under these conditions, is the most abundant HDL Apo-lipoprotein. Recombinant human Apo-SAA1 is an 11.7 kDa protein containing 104 amino acid residues.

Recombinant Human Apolipoprotein A-I (rHuApoA-I)

Apolipoprotein A-I participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT).

Recombinant HBV Surface Antigen-preS1 (rHBsAg-preS1)

Hepatitis B virus (HBV) is a human pathogen, causing serious liver disease. The HBV surface protein antigens (HBsAg) are comprised of three carboxyl co terminal HBs proteins termed large (LHBs), middle (MHBs) and small (SHBs, also called major) protein. LHBs and MHBs also share the highly hydrophobic, repetitive, membrane spanning S domain. In addition, LHBs has a 119 amino acid region called preS1.

Recombinant HBV Surface Antigen-preS2 (rHBsAg-preS2)

Hepatitis B virus (HBV) is a human pathogen, causing serious liver disease. The HBV surface protein antigens (HBsAg) are comprised of three carboxyl co terminal HBs proteins termed large (LHBs), middle (MHBs) and small (SHBs, also called major) protein. LHBs and MHBs also share the highly hydrophobic, repetitive, membrane spanning S domain. In addition, MHBs has a 55 amino acid region called preS2.

Recombinant Human Endocrine Gland-derived Vascular Endothelial Growth Factor (rHuEG-VEGF)

Endocrine gland-derived vascular endothelial growth factor (EG-VEGF), also called prokineticin 1 (PK1), is a member of the prokineticin family of secreted proteins that share a common structural motif containing ten conserved cysteine residues that form five pairs of disulfide bonds.
