SKU:: 363944
Purity:: Purified by immunoaffinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Rabbit
Immunogen:: Recombinant protein corresponding to Leu43-Leu364 of human LEFTY1 expressed in E. coli.
Format:: Supplied as a liquid in PBS, pH 7.4, 0.02% sodium azide, 50% glycerol.
Extra Details:: Vertebrates exhibit numerous left-right (L-R) asymmetries, such as the position of the heart and spleen on the left side. L-R polarity is determined early during development, around the presomite stage in mammals. Several genes have been shown to be expressed asymmetrically relative to the L-R axis. Meno et al. (1996, 1997) identified 2 transforming growth factor-beta-related genes, Lefty1 and Lefty2, that are expressed on the left side of developing mouse embryos.Kosaki et al. (1999) characterized 2 homologs of the murine Lefty1 and Lefty2 genes, which they designated LEFTY B and LEFTY A, respectively. Both genes encode proteins with 366aa. The deduced aa sequences of LEFTY B and LEFTY A are more similar to each other than to mouse Lefty1 or Lefty2.
