Besides different scales of AAV production, we can also offer novel AAV discovery services with AAV re-engineering capsids library and sub-library generation based on different strategies, customized AAV capsids screening and […]

Landscape of Advanced cell therapy

Lentivirus Protocol Download Cell therapy is a kind of medicine aiming to cure disease or alleviate disease symptoms via direct infusion or transplantation of cells, which can be autologous or allogeneic. With several decades’ development and optimization, immuno-oncology cells (such as T cells, nature killer cells, etc.), stem cells (embryonic stem cells, induced pluripotent stem […]

Small interfering RNA (siRNA) transfection

Small interfering RNA (siRNA) transfection Small interfering RNA (siRNA) contains 21-25 nucleotides, specific for target RNA. Once entry into cells, siRNAs can be recruited into a multi-protein complex, known as RNA induced silencing complex (RISC), which interacts with the target RNA to mediate mRNA degradation, thus knock-down or suppress the expression of target gene [45]. […]

Transfection in vivo

Transfection in vivo Transfection in vitro can be mediated by the non-viral reagents (such as liposome, polymer, nano-particle) or viral vectors (such as lentiviruses, adenovirus and AAV). Non-viral methods Formulations of liposome, polymer and nano-particle have been optimized for in vivo delivery, especially with the use of transfection enhancer and secondary injection. What’s more, the […]

Transfection in vitro

Transfection protocol Download Transfection in vitro Transfection in vitro can be mediated by the non-viral reagents (such as polymer, liposome, nano-particle) or viral vectors (such as lentivirus, adenovirus and AAV). Polymer-based transfection Polymer transfection is a technique used to deliver DNA or RNA into cells with biodegradable cationic polymer [6], such as DEAE-dextran or polyethylenimine […]

What is cell gene transfection

Transfection protocol Download In general, transfection is the process of delivering nucleic acids, such as DNA and RNA into eukaryotic cells, resulting in the expression or production of proteins or down-regulation of the targeted protein. Although not very common, protein transfection is also used to promote the rapid expression of target protein (such as Cas9 […]

CRISPR/Cas9?system?and Gene editing therapy

CRISPR/Cas9 protocol Download Gene editing, also called genome editing, is a group of technologies to change the sequence of DNA in the genome. Several approaches to genome editing have been developed, including Zinc Finger, TALEN, and CRISPR/Cas9. Compared with the other gene editing tools, CRISPR/Cas9 system is faster, cheaper, more accurate, and more efficient, showing […]
