• Product name
    Anti-Argonaute 5 antibody
  • Description
    Rabbit polyclonal to Argonaute 5
  • Specificity
    ab4723 detects a band of ~ 75 kDa in P19 embryonic carcinoma lysate. The predicted molecular weight of murine Argonaute 5 is 72 kDa according to Swissprot entry Q8CGT7. (This represents a partial sequence) Other bands of 85, 160 and 250 kDa are also detected which may be non-specific binding or alternatively may correspond to the full length Argonaute 5.

  • Relevance
    Argonaute proteins make up a highly conserved family whose members have been implicated in RNAi and related phenomena in several organisms. In addition to roles in RNAi-like mechanisms, Argonaute proteins influence development, and at least a subset are involved in stem cell fate determination. Argonaute proteins are ~100-kD highly basic proteins that contain two common domains, namely PAZ and PIWI domains (Cerutti et al. 2000). The PAZ domain, consisting of 130 amino acids, has been identified in Argonaute proteins and in Dicer (Bernstein et al. 2001a). Although it has no defined function, PAZ is thought to be a protein-protein interaction domain, potentially mediating both homo- and heterodimerization (Cerutti et al. 2000). There are several reports that Argonaute proteins, being highly basic, might bind RNA. Miwi, a murine homolog of Piwi, exists in a complex with its target mRNAs in vivo (Deng and Lin 2002). Furthermore, Drosophila Ago1 has been shown to bind ribohomopolymers in vitro (Kataoka et al. 2001). Of course, the involvement of Argonaute proteins in RNAi and related phenomena presupposes an interaction with RNA, either directly or indirectly. However, detailed studies of Argonaute structure and biochemistry will be required to reveal its precise function in RNA metabolism.

  • Predicted band size : 72 kDa

    This image was submitted as part or a review by Aarti Jagannath

    30µg of p19 murine embryonic carcinoma cell lysate was run on an SDS-PAGE and incubated for 12 hours with ab4723 (1/1000 dilution). A specific band of ~ 75 kDa is detected.


  • Anti-Argonaute 5 antibody (ab4723) at 1 µg/ml + F9 (Mouse embryonic carcinoma cell line) Whole Cell Lysate at 10 µg

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 72 kDa
    Observed band size : 75 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 100 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 2 minutes
