Phospho-Serine, -Threonine, & -Tyrosine Staining Kit

Immunocytochemistry Kit

Phosphorylation of specific tyrosine, serine, and threonine residues is an important post-translational modification for regulating the activity of proteins. Stimulation of a variety of cell signaling pathways activates the receptor and non-receptor kinases that mediate these protein modifications. Antibodies that can detect phosphotyrosine, phosphoserine, or phosphothreonine residues are excellent tools for characterizing changes in the post-translational state of a broad range of phospho-proteins. Immunoprecipitation of proteins of interest, followed by detection of phosphorylation using anti-phosphotyrosine or anti-phosphoserine/threonine antibody is commonly used to correlate changes in phosphorylation state with alterations in protein activity. Immunocytochemistry can also be used to examine changes in the level and localization of phosphotyrosine, phosphoserine, or phosphothreonine in cells after drug stimulation or during specific cell states.

Immunocytochemical labeling of phosphorylation in A431 treated with calyculin A (left panel) or pervanadate (right panel). The fixed cells were labeled with anti-Phosphoserine/threonine (PM3801) and anti-Phosphoserine/threonine (PP2551) (left panel) or with anti-Phosphotyrosine (PM3751) and anti-Phosphotyrosine (PP2221) (right panel). The antibodies were detected using appropriate secondary antibody conjugated to DyLight® 488 or DyLight® 594.

Mouse monoclonal, rabbit polyclonal, and secondary reagents are supplied in phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide. Store at –20°C. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.

KIT SUMMARY

The phospho-serine, -threonine, and -tyrosine kit can be used to examine the pattern of phosphoserine-threonine relative to phosphotyrosine, or relative to a target protein. The kit includes monoclonal and polyclonal antibodies to phosphoserine-threonine and phosphotyrosine along with Goat-anti-Rabbit conjugated to DyLight® 488 and Goat anti-Mouse conjugated to DyLight® 594 for dual labeling experiments.
