product information
Background LCY (lycopene beta-cyclase) is an enzyme (EC: of beta carotene biosynthesis pathway.  Catalyzes the double cyclization reaction which converts lycopene to beta-carotene and neurosporene to beta-zeacarotene. Protein is encoded by LCY1 gene.
Immunogen His-tagged, recombinant Arabidopsis thaliana LCY1 lycopene beta-cyclase, overexpressed in E.coli, UniProt:Q38933 , TAIR: AT3G10230
Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 50 ĩl
Reconstitution For reconstitution add 50 ĩl of sterile water.

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

application example

western blot using anti-LCY | lycopene beta-cyclase (chloroplastic)  antibodies

Total protein from Arabidopsis thaliana leaves, wilde type and Lut2 (Arabidopsis thaliana mutant devoid of lycopene-epsilon-cyclase, an enzyme at the same branching point catalyzed by lycopene-beta-cyclase (LCY)) corresponding to 0.5 µg of chlorophylls, were extracted with loading buffer (10% glycerol, 62.5 mM Tris pH 6.8, 2% SDS, 5% β-mercaptoethanol) and denatured at 100°C (boiling water) for 1 min.

Proteins were separated on 12% SDS-PAGE (Laemly) and blotted 1h to PVDF using tank transfer. Blots were blocked with blocking solution (PBS 1X, 0.2% w/v Tween, 5% powder milk) for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody diluted in blocking solution, at a dilution of from 1:1000 to 1:128000) for 1h at RT with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed 3 times for 10 min in blocking solution at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG alkaline phosphatase conjugated, diluted to 1:30 000 in blocking buffer for 1h at RT with agitation. The blot was washed 2 times for 10 min in blocking solution and once with PBS 1X solution for 10 min, then developed in developing buffer NBT/BCIP by manual agitation.

Mutant devoid of LCY is not available (not viable) and using lut2 mutant allowed to test if the antibody discriminates the two different cyclases.
