PsbA / Anti-D1 subunit of Photosystem II, DE-loop antibody

  Description:

Rabbit polyclonal antibody

  Background:

The D1 protein of Photosystem II (PSII), encoded by the psbA genes, is a subunit of PSII reaction center and is an indispensable component of oxygenic photosynthesis. Due to strongly oxidative chemistry of PSII water splitting, the D1 protein is prone to constant photodamage requiring its replacement, whereas most of the other PSII subunits remain ordinarily undamaged.

  Synonyms:

PsbA, 32 kDa thylakoid membrane protein, photosystem II protein D1

  Immunogen:

KLH-conjugated synthetic peptide of PsbA (15 aa from central section) derived from Arabidopsis thaliana (ATCG00020).

  Form:

Lyophilized

  Quantity:

150 µg

  Purification:

Immunogen affinity purified 

  Reconstitution:  

Reconstitution with 150 µl of 0.01M sterile PBS.
"Note: please spin tube briefly prior to opening it to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tube".

  Stability &
