M380A_PURE_Phosphothreonine_Antibody_1_121720.png
Whole cell lysates (15 μg) from untreated (-) or Calyculin A treated (+) (50 nM for 30 min) HeLa cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane and probed with 1.0 μg/mL (1:500 dilution) purified anti-Phosphoserine antibody (clone M380B) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG antibody (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH antibody (Cat. No. 607904) was used as a loading control at a 1:50000 dilution (lower). Lane M: Molecular weight marker.

    HeLa cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.5% Triton-X for 10 minutes, and blocked with 5% FBS for 30 minutes. Cells were then intracellularly stained with a 5.0 µg/mL (1:100 dilution) (panel A) purified anti-Phosphoserine antibody (clone M380B) overnight at 4°C, followed by incubation with Alexa Fluor® 594 goat anti-mouse IgG antibody (Cat. No. 405326) at 2.5 µg/mL. To demonstrate phospho-specificity of M380B, fixed and permeabilized HeLa cells were pre-treated with lambda protein phosphatase as a control prior to staining with M380B (panel B). Nuclei were counterstained with DAPI, and the image was captured with a 60X objective.

    Whole cell extracts (250 µg total protein) prepared from HeLa cells untreated (-) or treated (+) with Calyculin A (50 nM, 30 min) were immunoprecipitated overnight with 2.5 µg purified mouse IgG1, κ isotype ctrl antibody (Cat. No. 401401) or purified anti-Phosphoserine antibody (clone M380B). The resulting IP fractions and whole cell extract input (10%) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane and probed with purified anti-Phosphoserine antibody (clone M380B).

    PBMCs treated with (positive control, filled histogram) or without (negative control, open histogram) Cell Activation Cocktail (without Brefeldin A) (Cat No. 423301) were fixed and permeabilized using True Phos™ Perm Buffer (Cat No. 425401) and intracellularly stained with Purified anti-Phosphoserine (clone M380B) or Purified anti-Mouse IgG1, κ isotype control (Cat No. 400101) (open histogram, dashed line) (representative for untreated and treated PBMCs), followed by Alexa Fluor® 647 Goat anti-mouse IgG (Cat. No. 405322).

Description

Phosphorylation of specific serine residues is a post-translational modification event critical for regulating the activity of many proteins.  Protein phosphorylation events can alter protein function through a variety of molecular mechanisms, ranging from conformational changes that can stimulate or inhibit protein function to facilitating protein-protein interactions with binding partners. Antibodies that can detect phosphoserine residues are valuable tools for identifying novel phospho-sites and characterizing changes in the post-translational state of a broad range of phosphorylated proteins.
