How are Nanobodies produced?

Nanobodies are encoded by single gene fragments, are easily produced in micro-organisms and exhibit a superior stability compared to derivatives of conventional antibodies like Fabs or scFvs.

What is used in ChIP?

A chip is manufactured from a silicon (or, in some special cases, a sapphire) wafer, which is first cut to size and then etched with circuits and electronic devices. The electronic devices use complementary metal-oxide semiconductor technology.

What is input DNA in ChIP?

An “input” DNA sample is one that has been cross-linked and sonicated but not immuno-precipitated. Because “mock” ChIP’s can often produce relatively little amplifiable DNA input controls are more widely used to normalize signal from ChIP enrichment.

Why are nanobodies important?

Nanobodies can effortlessly infiltrate solid tumours, bind to a larger repertoire of regions on a target molecule, and leave the body without any trace, avoiding unwanted allergic response.

What are the benefits of using nanobodies as therapeutics compared with traditional monoclonal antibodies?

Nanobodies are composed of the target-binding fragments of monoclonal antibodies; they are significantly smaller in size than traditional monoclonal antibodies, have enhanced chemical properties, and they can access and lodge onto conventionally inaccessible regions on therapeutic targets.

Can nanobodies cross the blood brain barrier?

A study by Pierre Lafaye’s group (Li et al., 2012) reported that nanobodies with a high isoelectric point (pI) spontaneously cross the blood brain barrier. Such nanobodies not only gained access to the brain but were even found to penetrate cells and bind to intracellular proteins.

Why is ChIP useful?

Why is ChIP such a useful technique? ChIP dissects the spatial and temporal dynamics of the interactions between chromatin and its associated factors. The technique allows us to map minute-by-minute changes at a single promoter or follow a single transcription factor over the entire human genome.

Where are chips used?

Also known as semis, or chips, semiconductors can be found in thousands of products such as computers, smartphones, appliances, gaming hardware, and medical equipment.

How is ChIP-seq used?

ChIP-Seq identifies the binding sites of DNA-associated proteins and can be used to map global binding sites for a given protein. Protein-specific antibodies are used to immunoprecipitate the DNA-protein complex. The DNA is extracted and sequenced, giving high-resolution sequences of the protein-binding sites.
