Background

APP, also known as amyloid beta A4 protein, functions as a cell surface receptor and transmembrane precursor protein that is cleaved by secretases to form a number of peptides. Some of these peptides are secreted and can bind to the acetyltransferase complex APBB1/TIP60 to promote transcriptional activation, while others form the protein basis of the amyloid plaques found in the brains of patients with Alzheimer disease. Mutations in this gene have been implicated in autosomal dominant Alzheimer disease and cerebroarterial amyloidosis (cerebral amyloid angiopathy). Recombinant human APP protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.

FAQs for APP Protein (NBP1-99026). (Showing 1 - 1 of 1 FAQ).

  1. I'm planning to use NBP1-47438 in a labeling reaction that labels primary amines. I'm concerned about the Tris buffer competing with my protein for the label so I'm wondering if resuspending the protein in PBS will affect the protein very much compared to being in Tris?
    • Protein solutions must be free of any amine-containing substances such as Tris prior to carrying out a reaction to label primary amines. We do not have direct experience of labelling this particular antibody, however many standard labelling protocols do refer to dialysis against 10-20mM PBS. Depending on the labelling kit you are using, you may subsequently need to adjust the pH before carrying out the labelling reaction. Following the reaction, you may then store the conjugate under the same conditions used for the parent protein.
