Applications

Our Abpromise guarantee covers the use of ab64960 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/500 - 1/1000. Detects a band of approximately 40 kDa (predicted molecular weight: 34 kDa).

ELISA 1/20000.

Target

  • Function
    p35 is a neuron specific activator of CDK5. The complex p35/CDK5 is required for neurite outgrowth and cortical lamination. Activator of TPKII.
  • Tissue specificity
    Brain and neuron specific.
  • Sequence similarities
    Belongs to the cyclin-dependent kinase 5 activator family.
  • Post-translational
    modifications
    The p35 form is proteolytically cleaved by calpain, giving rise to the p25 form. P35 has a 5 to 10 fold shorter half-life compared to p25. The conversion results in deregulation of the CDK5 kinase: p25/CDK5 kinase displays an increased and altered tau phosphorylation in comparison to the p35/CDK5 kinase in vivo.
    Probably myristoylated. The Gly-2-Ala mutant is absent of the cell periphery, suggesting that a proper myristoylation signal is essential for the proper distribution of p35.
  • Cellular localization
    Cell membrane. In the primary cortical neurons, p35 is present in the peripheries and nerve terminals and Nucleus. Cytoplasm > perinuclear region. The conversion of p35 to p25 relocalizes the protein from the cell periphery to the cytoplasm, in nuclear and perinuclear regions. In the primary cortical neurons, p25 is primarily concentrated in the cell soma and is largely absent from neurites.

Thank you for your reply. I look forward to seeing your results from the current western blot. Please let me know if there is anything else I can

Answer

Thank you for providing the catalogue number of the antibody. The ab64960, anti-p35 antibody, is guaranteed to work in western blot and so is covered under our Abpromise, which is a guarantee that covers our antibodies for 6 months to work in the applications and species as stated on the data sheet. I was wondering if HEK-293 cells actually express p35, I ask as one of our other p35 antibodies, ab66064, was tested in transfecetd vs non-transfected HEK-293T cells, and no signal for p35 was detected in the non-transfected cells. Have you tried to run HEK-293 cell lysate samples and either HeLa cell or rat brain lysates and see if you get a signal from any of these samples? Please let me know if you have tried any of the tips from the previous email, or whether you have any information as to whether p35 is endogenously expressed in HEK293 cells. If there is anything else I can help with, please do not hesitate to contact
