Description
Human CellExp™ LEFTY-I, Human Recombinant is available at Gentaur for Next week delivery.
Plays a role in left-right asymmetry determination of organ systems during development
Biomolecule/Target:
Alternates names: Left-right determination factor 1, Left-right determination factor B, Protein lefty-1, Protein lefty-B
Synonyms: Human Recombinant LEFTY-I
Background Information: BioVision’s LEFTY-1 is expressed in human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 38 kDa. This cytokine is produced in a human cell expression system with serum-free, chemically defined media. Production in human 293 cells offers authentic glycosylation, contributing to stability in cell growth media. Lefty proteins function as an antagonist of the Nodal Signaling pathway. Proper functioning of Lefty is crucial to the proper development of the heart, lungs, spleen, and liver.
Reconstitution Instructions: Reconstitute in sterile water.
