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.

Amino acid sequence: N/A

Handling: Centrifuge the vial prior to opening.

Usage: For Research Use Only! Not to be used in humans
