Polyclonal Antibody against Human APPL1

Application: WB, IP, IH

Size: 0.1 mg

Host: Rabbit 


    APPL1, an adaptor protein containing an NH2-terminal Bin/Amphiphiphysin/Rvs (BAR) domain, a central pleckstrin homology (PH) domain and a COOH-terminal phosphotyrosine binding (PTB) domain [1] was originally identified as an interacting partner of Akt in a yeast two-hybrid assay using Akt2 as a bait [2]. APPL1 binds to a number of cell surface receptors (TrkA [3,4], DCC [5], adiponectin [6,7], FSH [8]) and intracellular signaling molecules (small GTPase Rab5 [9], GIPC [4] and inositol 5-phosphatase [10]), suggesting that APPL1 may act as a common relay to coordinate diverse signaling cascades. APPL1 potentiates insulin-mediated Akt activation by counteracting the effect of the Akt inhibitor TRB3 [11].


    Recombinant full-length human APPL1 expressed in E.coli.


    The antibody detects several types of APPL1 in different species such as human, monkey, mouse, rat etc. (about 85kDa).


    Liquid in phosphate-buffered saline (PBS).


    Store at –20°C for less than one week. For long-term storage, aliquot and freeze at -70°C. Avoid repeated freeze/defrost cycles.


    Western blot - This antibody can be used at 0.1-0.2 μg/mL with the appropriate secondary reagents to detect APPL1.

    ELISA - This antibody can be used at 2.0-5.0 μg/mL with the appropriate secondary reagents to detect APPL1.

    Immunoprecipitation See reference [6], [11].

    Immunostaining - This antibody can be used at 1.0-2.0 μg/mL with the appropriate secondary reagents to detect APPL1.
