Human ANGPTL7, His Tag (AN7-H52H5) is expressed from human 293 cells (HEK293). It contains AA Gln 27 - Pro 346 (Accession # O43827-1).
Predicted N-terminus: Gln 27
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 39.0 kDa. The protein migrates as 38-40 kDa and 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>85% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Angiopoietin-like 7 (ANGPTL7) is also known as Corneal-Derived Transcript 6 (CDT6), and is a secreted glycoprotein that is structurally related to the angiopoietins. It is expressed in the corneal stroma, trabecular meshwork, and sclera and is elevated in glaucoma aqueous humor. Recently, ANGPTL proteins, including ANGPTL-2, -3, -4, -5 and -7, are identified as growth factors in combination with SCF, Thrombopoietin, IGF-II and FGF acidic that enhance the expansion and engraftment of human and mouse hematopoietic stem cells.
