🧬Chromatin Immunoprecipitation Sequencing, ChIP-Seq🧬

Gene expression is key to understanding how a single genome can produce diverse cell types in a multicellular organism. Transcription factors bind to specific DNA sequences to regulate gene expression. Tfs interact with DNA wrapped around histones, which can be modified to promote or inhibit gene access. This intricate regulation maintains the balance that enables the proper function of different cell types.

ChIP-Seq is a technique that helps answer these questions. By pinpointing the exact locations on the DNA where transcription factors bind, we can get closer to understanding the regulatory network that controls gene expression.

⛓Cross-linking: Proteins are bound to DNA using formaldehyde.
🪓Fragmentation: DNA is broken into smaller pieces.
🧪Immunoprecipitation: Using specific antibodies, we isolate the DNA fragments bound by our protein of interest.
🧬Sequencing: These fragments are sequenced to identify the protein binding sites.

Antibody specificity
Sequencing depth
PCR duplication
The need for proper biological replicates
Ensuring high-quality experiments is crucial for accurate results.

Antibody Selection: Choose antibodies with high specificity to avoid cross-reactivity.
Sequencing Depth: Ensure you have enough reads to detect enriched regions reliably.
Controls: Always include control experiments (like IgG or knockout samples) to validate your results.
