Peptide target used to elicit this antibody is well conserved in all photoautotrophs except some cyanobacteria, some red algae and Cyanophora paradoxa, which contain a conserved substitution of a valine to an isoleucine. The performance of the antibodies has been confirmed against taxa containing both the valine andisoleucine variants.
Characteristics
Expected / apparent Molecular Weight of the Antigene: 82.7 / 55-60 kDa
Purification
serum
Immunogen
KLH-conjugated synthetic peptide derived from known PsaB sequences including Arabidopsis thaliana P56767, AtCg00340

Format
Lyophilized
Reconstitution
For reconstitution add 200 µL, of sterile water.
Handling Advice
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.

Background
AGI Code: ATCG00340 Photosystem I (PSI) of chloroplasts is a multisubunit membrane-protein complex that catalyzes the electron transfer from the reduced plastocyanin (or cytochrome c6) in the thylakoid lumen to the oxidized ferredoxin (or flavodoxin) in the chloroplast stroma. PsaB is a core protein of PSI complex. Synonymes: Photosystem I P700 chlorophyll a apoprotein A2, PSI-B
