Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
Reacts with a 30 kDa protein corresponding to human LEFTY. No reactivity occurs against 6X HIS tag. Significant sequence homology exists between the human and mouse forms of LEFTY. Cross reactivity is expected with mouse and rat forms of the protein. Reactivity with other sources has not been determined.
Left-right determination factor 1 and 2 (Lefty1/2) belong to the TGF-beta superfamily of proteins and are responsible for determination of left-right positioning of visceral organs during embryogenesis. Lefty1 acts as a regulator of Lefty2 and NODAL as the lack of the former resulted in bilateral expression of nodal, lefty2 and Pitx2 (a homeobox gene normally expressed on the left side and blocks the signal for leftness). Lefty2 may play a role in endometrial bleeding.
