Synthetic peptide AGSNENDDQNLGAKRR (linear) corresponding to aa166-181 of Lims1. Control peptide for L2000-01. Conjugated to BSA.
The expression of Lim1 is very similar to that of the PD gene aristaless. al is expressed in the most distal part of the leg discs, and in two rings in the peripheral and medial regions. Confocal immunofluorescence staining has shown that the expression of Lim1 and al are coincident in the most distal parts of the leg and antenna disc. Furthermore, there are similarities between the al and Lim1 mutant phenotypes, since in al mutants the claw organ, the sternopleural bristles in the leg and the arista are missing or reduced. A possible functional relationship between the two genes was explored. Since al is expressed earlier than Lim1, one possibility is that Lim1 expression is regulated by al. The expression of Lim1 was examined in al mutants, and Lim1 was found to be lost in the presumptive tip of the leg where both genes are co-expressed. In contrast, al expression is normal in Lim1 mutants. These results suggest that the Lim1 locus is regulated by the al gene, one possibility being that the Lim1 gene is a direct downstream target of the homeodomain Al protein (Pueyo, 2000).
Storage and Stability:Lyophilized powder may be stored at 4°C for short-term only. Stable for 12 months at -20°C. Reconstitute to nominal volume (see reconstitution instructions for peptides) and store at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
