Background

RARA (UniProtKB/Swiss-Prot entry P10276) is a receptor for retinoic acid, a vitamin A metabolite, which directly regulates gene expression in target cells by binding to specific DNA response elements. In the absence of its ligand, this receptor represses transcription through the recruitment of specific corepressors and of HDAC’s, whereas binding of retinioc acid causes the recruitment of coactivators and HAT’s. Translocations involving the RARA gene, often leading to a RARA/PML fusion protein, are a major cause of acute promyelocytic leukemia.

Storage/Stability

Store at –80°C for up to 2 years. Centrifuge after first thaw to maximize product recovery. Aliquot to avoid repeated freeze/thaw cycles. Aliquots may be stored at –20°C for at least one month.

Assay Conditions

ChIP results obtained with the antibody directed against RARA
ChIP assays were performed using NB4 cells, the antibody against RARA (Cat. # 25310) and optimized primer pairs for qPCR. Sheared chromatin from 6 million cells and 4 µl of antibody were used per ChIP experiment. QPCR was performed using primers specific for the TGM2, HMHA1, PRAM1 and H2B genes. Figure 1 shows the relative occupancy, calculated as the ratio + control/background for which the second exon of the MB gene was used.

ChIP-seq results obtained with the antibody directed against RARA
ChIP was performed as described above and the immunoprecipitated DNA was analyzed with an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 32 bp tags were aligned to the human reference genome (hg18) using the ELAND algorithm. Figure 2 shows the results of the complete chromosome 19 and two 50 kb region surrounding the HMHA1 and PRAM1 genes, respectively.

Determination of the antibody titer
To determine the titer of the antibody, an ELISA was performed using a serial dilution of the antibody directed against human RARA (Cat. # 25310). The plates were coated with the peptides used for immunization of the rabbit. By plotting the absorbance against the antibody dilution (Figure 3), the titer of the antibody was estimated to be 1:2,400.

Western blot analysis using the antibody directed against RARA
Human embryonic kidney cells (293T) were transfected with a RARA construct (lane 2) or with a negative control construct (lane 1) and analyzed by Western blot using the antibody against RARA (Cat. # 25310), diluted 1:750 in BSA/PBS-Tween. The molecular weight marker (in kDa) is shown on the left; the location of the protein of interest is indicated on the right.
