RIPAb+ STAU1 (Staufen 1)

32160702

NA.32

RIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation.
STAU1 (Staufen 1) is a RNA-binding protein implicated in the transport and/or localization of mRNA via the microtubule network to the rough endoplasmic reticulum.

Other species have not yet been tested.

Synthetic peptide from amino acids 2-51 of human STAU 1.
Epitope: a.a. 2-51

Immunoprecipitation from RIP lysate:
Representative lot data.
RIP lysate from HeLa cells (~2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using 5 µg of either a normal rabbit IgG, (Cat. #PP64B), or 5 µg of Anti-STAU1 (Staufen 1) antibody (Cat. # CS204405). Ten percent of the precipitated proteins (lane 1: rabbit IgG, lane 2: STAU1) were resolved by electrophoresis, transferred to nitrocellulose and probed with Anti-STAU1 (Staufen 1) antibody (Cat. # CS204405, 1:1000). Proteins were visualized using One-Step IP-Western kit (GenScript Cat. # L00232) .
Arrow indicates STAU1. (Figure 2).
Western Blot Analysis:
Representative lot data.
HepG2 cell lysate was resolved by electrophoresis, transferred to PVDF membranes and probed with Anti-STAU1 antibody (Cat. # CS204405, 1:1000 dilution). Proteins were visualized using a Goat Anti-Rabbit IgG conjugated to HRP and a chemiluminescence detection system.
Arrow indicates STAU1 (~63 kDa). (Figure 3).
Note: Uncharacterized bands appear at ~22 kDa and ~53 kDa in

RNA Binding Protein Immunoprecipitation:
RIP Lysate prepared from HeLa cells (2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using 5 µg of either a normal Rabbit IgGor 5 µg of Anti-STAU1 antibody and the Magna RIP^® RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
Successful immunoprecipitation of STAU1-associated RNA was verified by qPCR using RIP Primers ARF1, (Figure 1).
Please refer to the Magna RIP (Cat. # 17-700) or EZ-Magna RIP (Cat. # 17-701) protocol for experimental details.
