  • Relevance

    Phosphatidylinositol 4,5-biphosphate (PIP2) is a membrane phospholipid that has been implicated in a variety of cellular processes, including synaptic vesicle recycling and signal transduction pathways. PLCD4 hydrolyzes PIP2 to generate 2 second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3).


  • ab2335, staining PIP2 in non-polarized (left) and polarized (right) AX3 cells by Immunocytochemisry/ Immunofluorescence.

    Cells were fixed with formaldehyde, glutaraldehyde, and 0.01% Triton X-100 in PBS for 10 min. Samples were incubated with primary antibody at 1/100 dilution.

Thank you very much for your call last week, and I'm very sorry for the delay getting back to you.

I've just heard from the lab, and unfortunately ab2335 has not been tested for cross-reactivity with PIP3. The original clone was produced and tested by an outside lab, and we don't have the full ELISA or ICC protocols at this time.

I apologize that we don't have more information about this antibody, but if you have further questions or comments, or if there is anything else that we can do for you, please let me know and I'll be happy to help.
