Creative Biolabs Offers Comprehensive CAR-T Gene Packaging & Delivery Services

New York, April 25, 2019 With manufacturing and quality control of high standards, Creative Biolabs, now offers comprehensive CAR-T Gene Packaging & Delivery services, including virus based transfection, electroporation transfection, transposon based transfection.

Chimeric antigen receptor (CAR)-engineered T cell therapy with higher specificity and lower toxicity shows remarkable ability to eliminate various kinds of tumors, raising more and more attention in cancer treatment field. Aiming at genetically modifying T cells with designed CAR, Creative Biolabs flexibly adopts versatile methodologies to transfect CAR construction into T cells, which include virus based transfection, electroporation transfection, transposon based transfection.

1 Virus Based Transfection

The major advantages of viral vectors are relative ease of manufacture and production and capacity to stably integrate genetic material into the host genome. In Creative Biolabs, gamma retroviral vectors and lentiviral vectors are two common vectors used in Virus Based Transfection. Gamma-retrovirus (simple retrovirus, retroviral, MLV) contains a reverse transcriptase to enable the integration of artificial genes into the host genome in a stable status while lentivirus vectors is capable of mediating potent transduction and stable expression into dividing and non-dividing cells both in vitro and in vivo.

2 Electroporation Transfection

Electroporation can be used with most cell types, especially T cells, yielding a high frequency of both stable transformation and transient gene expression, which is characterized by easy operation and its applicability for transient and stable transfection of T cells. Moreover, electric transfection is easy and rapid to transfect a large number of T cells in a short time. In Creative Biolabs, electroporation is optimized by distributing the electrical pulse equally among the cells and maintaining a stable pH and modifying the pulse and field strength parameters to reduce the loss.

3 Transposon Based Transfection

Transposons are a non-virial alternative for stable gene transfer, including two main vectors, namely Sleeping Beauty (SB) and PiggyBac (PB). The SB system is a safer alternative to viral vectors due to its non-pathogenic origin, inherently low enhancer activity, and minimal epigenetic modifications at the insertion site, while PB system shows a large cargo capacity and more efficient transposition activity in preclinical studies. Scientists in Creative Biolabs optimize the transposon transfection to have higher capacity of carrying target DNA. Further, efficiency of gene movement and higher safety than the virial vectors make CARs production more reliable.
