product information

SPS (sucrose phosphate synthase, EC is the key enzyme of carbon flux into sucrose fixation in plants. It catalyzes the synthesis of sucrose-phosphate from UDP-glucose and fructose-6-phosphate predominantly in the cytosol of sucrose-source leaf tissue.


KLH-conjugated synthetic peptide derived from conserved region within plant SPS protein sequences, including Arabidopsis thaliana isoforms 1F Q94BT0, 2F, 3F and 4F. Oryza sativa Q67WN8, Solanum tuberosum Q43845

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum
Format Lyophilized in PBS pH 7.4
Quantity 200 ĩg
Reconstitution For reconstitution add 100 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

10 µg of total leaf protein from (1) A.thaliana,(3) Zea mays and (4) Hordeum vulgare extracted with PEB (AS08 300) as well as 10 µg cytosolic protein from (2) A.thaliana were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1.5h (30V) to nitrocellulose. Filters were blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-SPS (AS03 035A, 1:2000, 1h) and secondary anti-rabbit (1:20000, 1 h) antibody (HRP conjugated, Abcam) in TBS-T containing 2% low fat milk powder.  Antibody incubations where followed by washings in TBS-T (15, +5, +5, +5 min). All steps were performed at RT with agitation. Signal was detected with standard ECL (GE Healthcare) using a Fuji LAS-3000 CCD (90s, high sensitivity).
