Opis

General description

Protein phosphorylation and dephosphorylation are basic mechanisms for the modification of protein function in eukaryotic cells. Phosphorylation is a rare post-translational event in normal tissue, however, the abundance of phosphorylated cellular proteins increases several fold following various activation processes which are mediated through phosphotyrosine, phosphoserine or phosphothreonine (p-tyr/p-ser/p-thr). Many signal transduction pathways, such as the EGF, PDGF and insulin receptor systems, contain tyr/ser/thr kinase which phosphorylate specific tyr/ser/thr residues upon binding of ligands to their receptors. T cell antigen receptor complex or the receptors for some hemopoietic growth factors may stimulate these phosphorylation associated kinases, and cells transformed by viral oncogenes contain elevated levels of phosphorylated tyr/ser/thr.

Immunogen

Keyhole Limpet Hemocyanin (KLH) – conjugated phosphothreonine conjugates and Phosvitin.

Biochem/physiol Actions

Anti-phosphothreonine is species independent

By direct competitive ELISA methodology (antigen capture) the specificity of this antibody has been determined to be phosphothreonine. Binding of Ly-pT-Gly-HRP (0.2μg/100μL/well) to an anti-phosphothreonine coated microplate (0.5μg/100μL/well) is inhibited by 95% with the addition of 2-10 μg/mL anti-phosphothreonine. No inhibition is evident by inhibition of phosphoserine, phosphotyrosine, or threonine at concentrations of up to 1 mg/mL. Antibody AB1607 recognizes phosphothreonine, peptidyl-phosphothreonine, and threonine-phosphorylated proteins.

Physical form

ImmunoAffinity Purified

Purified rabbit polyclonal in PBS buffer, containing 50% Glycerol, 0.01% NaN3.

Preparation Note

Stable for 1 year at -20ºC in undiluted aliquots from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol-containing solutions to become frozen during storage.

Analysis Note

Control
Mouse brain lysate.

Routinely evaluated by Western Blot on Calyculin/Okadaic Acid treated HEK293 lysate.

Western Blot Analysis: 1:500 dilution of this lot detected PHOSPHOTHREONINE on 10 μg of Calyculin/Okadaic Acid treated HEK293 lysate.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
