ChIP-Seq mMAbs

Monospecific, Application-Tested &
Affinity-Purified Transcription Factor Antibodies

CDI launches its line of monospecific, affinity-purified monoclonal antibodies to several human transcription factors. This initial offering is highly suited for ChIP sequencing - the analysis of protein-DNA interactions.

CDI utilizes its HuProt™ Human Proteome Microarray for validating the specificity of the final product. These antibodies have been screened for cross-reactivity against thousands of human proteins (~87% of the human proteome).

Be Specific. If you’re grant-writing, publishing or manufacturing...
make CDI mMAbs part of your discovery and development success.

Quality Assurance - HuProt TM Microarray Specificity
(Representative Data)
antibody validation and quality assurance

Microarray Analysis: Anti-Human SMAD4 (clone R516.2.1D12) specificity was evaluated using CDI HuProt™ Human Proteome Microarray and subsequently analyzed with GenePix Pro Image Acquisition and Analysis Software, the benchmark tool for the acquisition and analysis of microarray images. The top 3 “hits” were identified by cross- reference to the array map which stores the exact location of each protein. The expected target, SMAD4, is ranked #1 and is considered monospecific. Signals ranked beyond #1 are statistically insignificant and not displayed.

antibody specificity data

Statistical Evaluation: GenePix data points (from above) were analyzed in terms of signal strength and ranked accordingly. The value shown for rank #1 and rank #2 indicate that Anti-Human SMAD4 (clone R516.2.1D12) is monospecfic. Rankings 2 through the remainder of the array are essentially equivalent to non-specific background signal.

A-Score (Affinity Score) is the normalized signal intensity of spots on the HuProt Array. S-Score (Specificity Score) S = A(Rank1) - A2(Rank2). A- and S-scores greater than 3 standard deviations over the next listed target are deemed statistically significant and indicate highly specific antibodies with high affinity. In the data above, the difference between Rank 1 and Rank 2 is 87.82. (standard deviations). This indicates that the antibody is monospecfic for SMAD4.

Validated Applications - ChIP-Seq (Representative Data)
ChIP-Seq analysis

ChIP-Seq Analysis: The ChIP was performed with chromatin from 10 million HepG2 cells and 3 μg of Anti-SMAD4 (cloneID #R516.2.1D12) antibody. The ChIP DNA was sequenced on an Illumina HiSeq platform and read counts were calculated at consecutive 100 bp bins across the human genome hg19. Normalized read-count levels for ChIP-seq of SMAD4 (R516.2.1D12_ChIP) and control (R516.2.1D12_IN) around the SKIL and JHDM1D loci are displayed in the CisGenome browser.
