A BALB/c mouse was immunized with a recombinant form of 6X HIS tagged human LEFTY.
Store LEFTY2 antibody at 4 grades C or -20 grades C. As with all antibodies avoid freeze/thaw cycles.
If you buy Antibodies supplied by proscience they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
LEFTY2 monoclonal antibody was made against recombinant LEFTY2 (Human). Hybridoma: Produced by the fusion between BALB/c mouse splenocytes and mouse Sp2/0 myeloma cells using conventional hybridoma technology.
During vertebrate embryogenesis, a left-right axis is established. Secreted growth factors of the TGF-β family, including gene products derived from nodal, lefty-1 and lefty-2, play crucial roles in establishing left-right asymmetries. TGF-β (Transforming growth factor-beta) is a pleiotropic cytokine that regulates growth and differentiation of diverse types of cells. TGF-β actions are directed by ligand-induced activation of TGF-β receptors. Complexes formed move into the nucleus, where they act as components of a transcriptional complex. Lefty, a novel member of the TGF-β superfamily, inhibits TGF-β signaling. Lefty acts to inhibit phosphorylation of Smad2 following activation of the TGF-β receptor. Lefty also inhibits events downstream from R-Smad phosphorylation. Lefty provides a repressed state of TGF-β-responsive genes. The Lefty family is comprised of Lefty 1 and Lefty 2 in mouse, and Lefty A and Lefty B in humans. Members of the TGF-β superfamily require processing for their activation. Cleavage is therefore an essential step for Lefty activation. Lefty is synthesized as a large inactive precursor (42 kDa) that must be endoproteolytically processed to release the bioactive polypeptide (28 kDa and 34 kDa forms). The 28 kDa form induces MAPK activity.
