Target of this antibody:
Alternative names of antibody target:
CTBP, CTBP1, CTBP-1, C-Terminal Binding Protein 1
CtBP1 is a cellular phosphoprotein that associates with various proteins and functions as a corepressor of transcription. CtBP1 and the related protein CtBP2 are characterized as C-terminal binding protein of adenovirus E1A, and they preferentially associate with the E1A via a 5-amino acid motif, PLDLS, to repress E1A induced oncogenesis and cellular transformation. CtBP1 is expressed from embryo to adult, but CtBP2 is mainly expressed during embryogenesis. During skeletal and T-cell development, CtBP1 and CtBP2 associate with the PLDLSL domain of ∂EF1, a cellular zinc finger-homeodomain protein, and thereby enhances ∂EF1 induced transcriptional silencing. In addition, CtBP complexes with CtIP, a protein that recognizes distinctly different protein motifs from CtBP. CtIP binds to the BRCT repeats within the breast cancer gene BRCA1 and enables CtBP to influence BRCA1 activity. CtIP/CtBP binding to BRCA1 inhibits the transactivation of the p21 promoter, and it is critical for regulating p21 transcription in response to DNA damage.

Form of antibody:
Formulation of this antibody:
100 µl affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 1% BSA and 0.02% thimerosal.
This antibody has been succesfully tested for use in following methods:
Western blotting (1:500 – 1:2000). However, the optimal concentrations should be determined individually. HeLa nuclear extract (Cat.# 1641-1) can be used as a positive control. The antibody recognizes the CTBP1 of human and mouse origins. Reactivity to other species has not been tested.
Shelf time: 12 months in temp.: -20 deg.C
How to handle this antibody:
The antibody solution should be gently mixed before use.
This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
