The Power of Global Antibodies

• Global Antibodies are raised against peptides conserved  in the target proteins across a range of species. This intelligent design generates antibodies with quantitative target recognition across a defined  range of species.
• Global Quantitation Standards allow accurate measurement of levels  of the target protein from any species within the defined taxonomic range  because their target recognition region is precisely the same.
• Global Antibodies reliably measure the levels of key proteins even  in uncharacterized species or mixed communities.

Some Antibodies and Standards; check agrisera.com/shop for a complete list.

Global Antibodies

• RbcL; Rubisco Large Subunit, Global Antibody (chicken) recognizing Form I L8S8
• RbcL; Rubisco Large Subunit, Global Antibody (rabbit) recognizing both Form I L8S8 and Form II L2
• Rubisco is a major protein pool in most oxygenic photoautotrophs; quantitation of RbcL allows estimation of the flux capacity for C fixation.
• PsbA: PSII D1 subunit
• Track the content of intact PSII in studies of photosynthesis, photoinhibition and stress physiology.
• PsbB: PSII CP47, Global Antibody (rabbit)
• A stable PSII subunit, use in conjunction with the PsbA antibody to study the PSII repair cycle.
• PsaC: PSI subunit
• Track PSI levels, and PSI:PSII ratios in conjunction with the PsbA or PsbB antibodies.
• AtpB: ATP Synthase beta subunit of F1 complex, conserved across chloroplasts, mitochondria, cyanobacteria and many other bacteria,  Global Antibody (chicken)
• GlnA: Glutamine Synthetase, bacterial form, Global Antibody (chicken)
• Glutamine synthetase is the main connection point between inorganic and organic combined nitrogen.
• NifH: Nitrogenase subunit, Global Antibody (chicken)

Quantitation Standards

• RbcL: suitable for use with both the Form I and Form I + II antibodies
• PsbA: PSI:PSII ratios determined with our Global antibodies and quantitation standards match well with independent literature estimates.
• PsaC: PSI:PSII ratios determined with our Global antibodies and quantitation standards match well with independent literature estimates.
• AtpB
