Also for EIF3E (NM_008388)
|This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a region near the C-terminus of mouse EIF3S6/Int6.|
|mouse, human, rat, dog, bovine, monkey
||ELISA: 1:90,000, WB: 1:1,000
|0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2|
|This antibody is suitable for Cancer, Immunology and Nuclear Signaling research. Int6 is a candidate tumor suppressor in multiple neoplasms, and in particular, breast and lung cancers. The Int6 locus was initially identified as a common insertion site (CIS) in a genetic screen for transforming sequences in a breast cancer mouse model system. Insertion of mouse mammary tumor virus (MMTV) into this locus results in the production of an amino-terminal truncated gene product. Expression of the truncated Int6 product corresponds to cellular transformation in both in vivo and in vitro systems. This gene product plays a role in regulating translation initiation and is a component of the eIF3 translation initiation complex. There is evidence that suggests that Int6 may impart a negative role in the general translational machinery while promoting an increase in the expression of a subset of stress-responsive genes. Taken together, it is of great interest to further study the mechanism by which Int6 is involved in regulating cell growth.

WB using Anti-eIF3S6/Int6 antibody shows detection of endogenous eIF3S6/Int6 in whole cell extracts from murine (HC-11 and NIH3T3), monkey (CV-1 and Cos-1), and human (HEK293T) cell lines as well as over-expressed eIF3S6/Int6 (control transfected flag-tagged Int6).The identity of the higher and lower molecular weight bands is unknown. The band at ~48 kDa, indicated by the arrowhead, corresponds to flag-tagged EIF3S6/Int6. Primary antibody was used at 1:1000.
Western blot using affinity purified anti-eIF3S6/Int6 antibody shows detection of endogenous eIF3S6/Int6. Specific staining is not present in lysates containing lentiviral knockdown vectors (shRNA #1 and #2. Control vectors, specifically a scrambled sequence (Ctl NS) and a sequence against an unrelated gene (Ctl #2), were also used. Personal communication, J.Lee, NCI, Bethesda, MD.
