RIPAb+ Upf1 - RIP Validated Antibody and Primer Set

Upf1 is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. Upf1 is located only in the cytoplasm. When translation ends, it interacts with the protein that is a functional homolog of yeast Upf2p to trigger mRNA decapping.

~125 kDa

KLH-conjugated synthetic linear peptide corresponding to Upf1.

Immunoprecipitation from RIP lysate:
Representative lot data.
RIP lysate from HeLa cells (~2 X 10E7 cell equivalents per IP) was subjected to immunoprecipitation using either 7 µL of a normal rabbit IgG or 7 µL of Anti-Upf1 antibody.
Ten percent of the precipitated proteins (lane 1: rabbit IgG, lane 2: Upf1) were resolved by electrophoresis, transferred to PVDF and probed with anti-Upf1 antibody (1:2000).
Proteins were visualized using One-Step IP-Western kit (GenScript Cat. # L00232)
Arrow indicates Upf1 (~125 kDa) (Please see figures).

Western Blot Analysis:
Representative lot data.
U2OS cell lysate was resolved by electrophoresis, transferred to PVDF membrane and probed with anti-Upf1 (0.5 μg/mL).
Proteins were visualized using a donkey anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system.
Arrow indicates Upf1 (~125 kDa) (Please see figures).

FOR: GAC CAC GAT CCT CTA CAA GC
REV: TCC CAC ACA GTG AAG CTG ATG

Format: Purified

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

RNA Binding Protein Immunoprecipitation:
RIP Lysate prepared from HeLa cells (2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using either 7 µL of a normal rabbit IgG or 7 µL Anti-Upf1 antibody and the Magna RIP^® RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
Successful immunoprecipitation of Upf1-associated RNA was verified by qPCR using RIP Primers ARF1 (Please see figures).
Please refer to the Magna RIP (Cat. # 17-700) or EZ-Magna RIP (Cat. # 17-701) protocol for experimental details.

Control
Includes negative control normal rabbit IgG antibody and control primers specific for the cDNA of human ARF1.
