(colorimetric). Do not use milk as a blocking agent or in diluents, as milk casein is phosphorylated at several serine residues. BSA is recommended instead.

ICC/IF Use a concentration of 1 µg/ml.


  • 関連性Changes in the serine/threonine phosphorylation state of a protein in response to various external stimuli can have profound effects on cellular signal transduction, apoptosis and carcinogenesis. The reagents, including phosphorylated protein/peptides, antibodies against the phosphospecific amino acid, are important tools to explore the activation of serine, threonine or tyrosine containing proteins. An aberrant protein phosphorylation is a hallmark of human disease, and the enzymes, particularly protein kinases, which control protein phosphorylation are recognized as a major new drug target family.

Anti-Phosphoserine antibody [3C171] 画像

  • ICC/IF image of ab17465 stained MCF-7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab17465, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your enquiry. I was able to obtain an image. I'll send it to you in a separate email as I cannot attach it here. You will see that the antibody was tested at 1:200 in a Drosophila melanogaster whole tissue lysate (40ug/lane). There ...

Thank you for your enquiry. I have updated the specificity statement for ab17465 with the following information from the source of the antibody: Recognizes phosphorylated serine both as free amino acid and when coupled to carriers such as BSA or ...

I'm sorry to hear you are having problems with ab17465. Could you please clarify what you mean with "no signal despite positive controls on western"? Did the antibody work on cell lysate in WB and stop working when your protein of interest was immu...

The immunogen was phosphoserine-KLH and the antibody recognizes free phosphoserine or phosphoserine conjugated to a carrier such as KLH or BSA. There is no immunizing peptide; just a phosphorylated amino acid.
