Vaccines have long been used to fight against infectious diseases and most currently available vaccines were empirically designed. However, immune evasion by pathogens often lead to difficulty in vaccine development. Revolutionary changes happened in the approach to vaccine design and development in the last decade.
Vaccine test play a crucial role in the assessment of the potency and safety of human vaccines. Efficient translation from basic research to clinical therapies will depend on the availability of appropriate animal models to address every problem that arises during vaccine development.、
Well vaccine customized development of a vaccine project requires an experienced partner who understands the unique complexity presented by this important research area. Close cooperation between professional laboratories and clinical research teams is essential for ensuring good sample handling, tracking and data reporting, and successful completion of vaccine research
Vaccines can generally be classified as Live Attenuated Vaccine, Inactivated Vaccine, Subunit Vaccine, Vector Vaccine, Conjugate Vaccine, DNA and RNA Vaccine and more.
In general, the T cell phagocytosis assay can be divided into two categories, in vivo and in vitro. Both of them are always based on fluorescence. In vivo assay has advantages to be more useful and credible, while in vitro phagocytosis assay could give insights during an early stage in a very short timeline.
The typical structure of a CAR molecule includes a single chain variable fragment (scFv), a spacer, a transmembrane domain (TM) and an intracellular signaling domain. The scFv is derived from monoclonal antibody (mAb), which can specifically recognize the target protein on tumor surface and subsequently transduct activation signal into chimeric antigen receptor t-cells.
Flow cytometry is a widely used laser- or impedance-based method for CAR T Characterization by analyzing the expression of cell surface and intracellular molecules, characterizing and defining different cell types in a heterogeneous cell population, assessing the purity of isolated subpopulations and analyzing cell size and volume.
Single-cell sequencing (SCS) can be employed for analyzing the genetic polymorphisms of individual cells at a genome-wide level. Basically,there are three steps including obtaining single cell of interest, extraction and amplification of genetic materials, and descriptive analysis from CAR sequencing data.

As a leading CAR T technology provider, Creative Biolabs has established CellRapeutics™ Chimeric Antigen Receptor (CAR) Technology platform. Our elite scientists have broad experience in CAR construction, which can supply the best service for you.
CAR T biomarker provides the most prominent signal of cancer cells for distinguishing from normal cells and the most effective target for immune recognition and destruction.
To accelerate the drug discovery and development process, Creative Biolabs offers a broad range of early development service, especially for TCR engineered T cell biomarker identification and selection, design, construction, and analysis. Moreover, our one-stop TCR T development services also provide you the preclinical test.
Several CAR-T libraries are generated not only for blood cancer antigen CD19, but also for solid tumors against different antigens, such as Her2, Her3, EGFR, FGFR1, VEGFR, etc. The selected stable clones can be used in clinic trails immediately, thus making this technology more powerful and attractive in CAR T therapy.

Aiming at genetically modifying T cells with designed CAR T gene, our scientists flexibly adopt versatile methodologies to transfect CAR construction into T cells, such as packing and transfection with virus based transfection methods.
Altering the specificity of T cell receptor (TCR) is one of the popular strategies to genetically modify T cells to enhance the tumor-killing activity of T cells. With high-affinity TCR technology, Creative Biolabs is capable of identifying the candidate target tumor antigen and the sequence of tumor-specific TCR to create tumor-specific T cells.
