Validation Data Gallery

• 

  WB analysis of A549 using 28130-1-AP (same clone as 28130-1-PBS)

  A549 cells were subjected to SDS PAGE followed by western blot with 28130-1-AP (eRF3a/GSPT1 antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

• 

  WB analysis of HepG2 using 28130-1-AP (same clone as 28130-1-PBS)

  WB result of eRF3a/GSPT1 antibody (28130-1-AP; 1:4000; incubated at room temperature for 1.5 hours) with sh-Control and sh-eRF3a/GSPT1 transfected HepG2 cells. This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

• 

  WB analysis of PC-3 using 28130-1-AP (same clone as 28130-1-PBS)

  PC-3 cells were subjected to SDS PAGE followed by western blot with 28130-1-AP (eRF3a/GSPT1 antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

• 

  WB analysis of SKOV-3 using 28130-1-AP (same clone as 28130-1-PBS)

  SKOV-3 cells were subjected to SDS PAGE followed by western blot with 28130-1-AP (eRF3a/GSPT1 antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human ovary cancer using 28130-1-AP (same clone as 28130-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human ovary cancer tissue slide using 28130-1-AP (eRF3a/GSPT1 antibody) at dilution of 1:1000 (under 20x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human stomach using 28130-1-AP (same clone as 28130-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human stomach tissue slide using 28130-1-AP (eRF3a/GSPT1 antibody) at dilution of 1:500 (under 20x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

• 

  IF Staining of HeLa using 28130-1-AP (same clone as 28130-1-PBS)

  Immunofluorescent analysis of (-20°C Ethanol) fixed HeLa cells using eRF3a/GSPT1 antibody (28130-1-AP) at dilution of 1:400 and CoraLite®488-Conjugated AffiniPure Goat Anti-Rabbit IgG(H+L). This data was developed using the same antibody clone with 28130-1-PBS in a different storage buffer formulation.

Background Information

The eukaryotic Release Factor 3 (eRF3) is a GTPase that associates with eRF1 in a complex that mediates translation termination. Eukaryotic release factor 3 (eRF3) has many functions in eukaryotic cells, such as controlling the regulation of the cell cycle at the G1 to S phase transition, and regulating protein synthesis as a GTP dependent stimulator of eRF1 in translation termination. It was also reported to play a key role as an initiator of the mRNA degradation machinery in the recycling of ribosomes in successive cycles of translation,and probably also in transcription regulation. eRF3a, also known as GSPT1, is one subunit of eRF3(PMID:15917414,12923185). It involves in translation termination in response to the termination codons UAA, UAG and UGA and stimulates the activity of ERF1. eRF3a/GSPT1 exists some isoforms with MV 69 kDa and 56 kDa. Identification of a processed form of eRF3a/GSPT1 as a BIR3-binding protein-Using a GST-BIR3 fusion protein as an affinity reagent to purify new IAP binding proteins from extracts of human cells and mouse tissues, we previously isolated 3 proteins of molecular weights 23, 38 and 80 kDa. 80 kDa band confirmed that it is a processed form of the human GSPT1/eRF3a protein, lacking the first 69 residues(PMID: 12865429).
