Plant/Algal cell antibodies / Oryza sativa

product information

Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of CO2 fixation in photosynthesis. It is one of the most abundant proteins on Earth and its homology has been demonstrated from purple bacteria to flowering plants.

KLH-conjugated synthetic peptide derived from all known plant,algal and cyanobacterial RbcL (Rubisco large subunit of Rubisco Form I) sequences, including Arabidopsis thaliana (AtCg00490), Sychococcus sp. Q3ALL1

store at 4°C; make aliquots to avoid working with a stock. Please, Remember to spin tubes briefly prior to opening them to avoid any losses that might occur from liquid material adhering to the cap or sides of the tubes.

AS01 017S | Rubisco protein standard for quantitation

AS03 037 | Anti-RbcL rabbit antibody

secondary antibody to use with this product:

Goat anti-chicken IgY (H&L), HRP conjugated

or

Goat anti-chicken IgY (H&L), ALP conjugated

peptide target used to elicit this antibody is not conserved in type II Rubisco found in dinoflagellates and some photosynthetic bacteria. For those species product AS03 037 is recommended.

This antibody detects RbcL protein from 102.6 fmoles and has been used as a control to ensure adequate permeabilization and fixation of toxic cyanobacterial cells in immunolabeling experiments (method based on: Orellana & Perry (1995) J Phycol 31: 785-794).

Antibody has been used in immunolabelling of intact cyanobacterial cells fixed with ethanol using a secondary anti-IgY antibody conjugated with a fluorochrome.
