RNAi Protocol

Experiment Tags: RNAi

Experiment Summary: RNAi consists of inititation and effector steps. At inititation steps, the dsRNAs get processed into 21-23 nucleotide (nt) small interfering RNAs (siRNAs) by an RNase III-like enzyme called Dicer.

Recombinant Lentivirus Production Protocol

Experiment Tags: Lentivirus, Recombinant Lentivirus

Experiment Summary: Transient transfection method is now widely used for generation of recombinant lentivirus. Envelope plasmid, packaging plasmid and recombinant lentivirus plasmid cotransfect 293T cells to get producing cells.

PERT Assay Protocol

Experiment Tags: PERT Assay, Product-enhanced RT

Experiment Summary: Sensitivity was greatly increased when a PCR amplification step of the synthesized cDNA was introduced prior to product detection. These types of assays are known as product-enhanced RT (PERT) assays.

Limiting Dilution Protocol

Experiment Tags: Dilution, Cell

Experiment Summary: Limiting dilution analysis attempts to determine the frequency of cells having a particular function that are present in a mixed population of cells. So limiting dilution analysis is an easy-operated method that used to measure the abundance of cells able to perform a particular function.

Lentivirus Transduction Protocol

Experiment Tags: Lentivirus, Lentivirus Transduction

Experiment Summary: Lentivirus is a modified HIV virus that must be handled with caution although it cannot replicate in a host.

Designing sgRNA using CRISPR Protocol

Experiment Tags: sgRNA, CRISPR

Experiment Summary: Selection of sgRNAs for an experiment needs to balance two aspects: maximizing on-target activity while minimizing off-target activity, which sounds obviously but can often require thorough decisions.

Gene Overexpression in Cell Lines Protocol

Experiment Tags: Cell, Cell Line

Experiment Summary: The fundamental principle is to add regulatory elements to the upstream of the target gene through artificial construction, so that genes can be transcribed and translated efficiently under controlled conditions.

Fosmid Library Construction Protocol

Experiment Tags: Fosmid Library, Library, Library Construction

Experiment Summary: The fosmid system has been widely used in the construction of large-insert genomic libraries. Fosmid clones are similar in insert size comparing with cosmid clones and smaller than that in BAC and yeast artificial chromosomes (YAC).

CRISPR Plasmid Transfection Protocol

Experiment Tags: CRISPR, CRISPR Plasmid

Experiment Summary: The CRISPR/Cas9 system has two critical parts: sgRNA sequence and Cas9 sequence. These two sequences could be cloned into separated plasmids or combined into one plasmid, each format has its own set of advantages and shares a similar delivery procedure.

Codon Optimization Protocol

Experiment Tags: Codon Optimization, Codon

Experiment Summary: Codon optimization is one of the key steps in achieving the high level expression of target gene. There are some key factors for consideration including transcription efficiency, translation efficiency, gene synthesis and protein folding.
