Human ANGPTL4/Angiopoietin-like 4 Protein

Product Info

Recombinant Human ANGPTL4/Angiopoietin-like 4 Protein is expressed from Expi293 with His tag at the N-terminal. It contains Pro166-Ser406.[Accession | Q9BY76-1]

Molecular Weight

The protein has a predicted MW of 28.2 kDa. Due to glycosylation, the protein migrates to 30-40 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Supplied as 0.22μm filtered solution in PBS (pH 7.4).


The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Human Angiopoietin-like 4 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


The purity of Human Angiopoietin-like 4 is greater than 95% as determined by SEC-HPLC.

SPR Data

Human LILRB2 captured on Protein A chip, can bind Human ANGPTL4,His Tag with an affinity constant of 13.8nM as determined in a SPR assay (Biacore T200).


Candidates for this common regulatory system include signals mediated by peroxisome proliferator-activated regulator and its response factor, angiopoietin-like 4. The expression and bioactivity of angiopoietin-like 4, an adipocytokine that was originally reported to have an angiogenic function, have been detected not only in the vascular system and adipose tissue but also in rheumatoid joints.
