General description

Protein phosphorylation is normally associated with protein modification in signaling pathways and may be useful in pathophysiology and treatment of major neuropsychiatric disorders. Antibodies against phospho-threonine have been used to establish stability of the phosphorylated forms of proteins that may be involved in many different types of signaling. Phospho-threonine antibody is used to measure phosphorylation levels of PSII reaction center proteins D1, D3 and chlorophyll a binding protein CP43.


KLH-conjugated linear peptide corresponding to Threonine.


Immunoprecipitation Analysis: 10 µg of this antibody immunoprecipitated Threonine from 100 µg of A431 cells stimulated with calyculin/okadaic acid.

Immunocytochemistry Analysis: 1:500 dilution from a previous lot detected Threonine in A431, NIH/3T3, and HeLa cells.
Research Category
Research Sub Category
General Post-translation Modification
This phospho-Threonine antibody is validated for use in WB & ICC for the detection of the phospho-Threonine protein.


Evaluated by Western Blot in calyculin/okadaic acid treated and untreated A431 cell lysates.

Western Blot Analysis: 0.5 µg/mL of this antibody detected Threonine on 10 µg of calyculin/okadaic acid treated and untreated A431 cell lysates.
