Levels of ANGPTL4 in sera from RA patients and controls after correction for the false positive reactions to rheumatoid factor (RF).(A) ANGPTL4 was measured in sera from 57 patients with rheumatoid arthritis (RA) and 43 matched controls by ELISA using DY3485 kit with lot IV detection antibody. (B) ANGPTL4 was measured as in (A) in sera from RF+ (n = 33) and RF- (n = 20) patients with RA. The means ± SD are indicated.

Background: Angiopoietin-like Protein 4/ANGPTL4

Angiopoietin-like, also known as angiopoietin-related proteins, are structurally related to the angiopoietins. They are secreted proteins with N-terminal coiled-coil domains and C-terminal fibrinogen-like domains. Unlike the angiopoietins, ANGPTLs do not bind Tie-2. Seven ANGPTL proteins have been identified (ANGPTL1 through 7).

Alternate Names
