Identity Testing
Identity testing is required for newly established cell lines. Isoenzyme analysis is used to confirm the identity of the species of a cell line. Alternative methods for identity testing include DNA fingerprinting, STR analysis and karyology.

Virological Safety Testing
A broad range of viruses is susceptible to affecting human cell lines. We can provide in vivo/vitro virus saftey assays by utilizing various animal systems. These viruses include: adventitious viruses, bovine viruses, human and simian viruses, porcine viruses, retrovirus and rodent viruses.

Genetic Stability Testing
We perform cell genetic stability studies under ICH guidelines. We can provide guidance on the appropriate testing program upon your requirements.

PROTOCOL
1. Thaw CAR-Jurkat cell samples quickly in a 37°C water bath until all visible ice has melted. Thaw time for a 1 ml sample in a cryovial is 2-3 minutes. Cryovials should be cool to the touch when removed from the water bath.
2. Dilute cell/medium mixture immediately with CAR-Jurkat cell culture medium. This can be performed in a single step. The dilution medium should be between 20-37°C. A dilution ratio of 1:10 (sample:medium) or greater is recommended.
3. Plate cells appropriately according to the experimental conditions of assays.
4. Culture the control lentivirus CAR-Jurkat cells or use immediately.
Note: Jurkat cells that are used immediately after thawing have the highest level of viability.

Application
1. Compound screening;
2. Antibody screening;
3. Co-stimulatory and activation domain comparison;
4. Checkpoint inhibitors screening;
5. Safety switches and regulators of CAR-Jurkat functions study;
6. Pre-clinical study in vivo models;
7. CAR-Jurkat signaling, tumor microenvironment;
8. Proof of concept studies for clinical trials;

CAR Signaling Cassetes
CD28
CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatorysignals required for T cell activation and survival. CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2) proteins which are expressed on antigen-presenting cells(APC). CD28 modulates the primary TCR/CD3ζ signal in a different fashion than the late costimulatory elements OX40 and 4-1BB. CD28 enhances the expression of downstream regulators that impact on T-cell proliferation, death, differentiation, and effector functions. CAR+ T cells containing the CD28 endodomain showed strikingly enhanced sustained T cell activation, growth, survival. And CD28 results in a brightly expressed, stable receptor as the transmembrane domain. Including CD28 costimulatory domains in CARs led to enhanced anti-malignancy efficacy.
OX40
OX40, also known as CD134 or TNFRSF4 is a member of the TNFR-superfamily of receptors which is not constitutively expressed on resting naïve T cells, unlike CD28. OX40 is a secondary co-stimulatory immune checkpoint molecule, expressed after 24 to 72 hours following activation. The interaction between OX40 and its binding partner, OX40L (CD252) plays an important role in antigen-specific T-cell expansion and survival. OX40 and OX40L also regulate cytokine production from T cells and modulate cytokine receptor signaling. OX40 cosignaling in CAR improve redirected T-cell effector functions and enhance anti-tumor activity.
CD3ζ
CD3ζ, also known as T-cell receptor zeta, which together with T-cell receptor and CD3γ, δ, ε chain, forms the TCR-CD3 complex. ζ was expressed independently from the complex. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. CD3-zeta,which contains 3 ITAMs, is the most commonly used endodomain component of CARs. It transmits an activation signal to the T cell after antigen is bound. CD3-zeta may not provide a fully competent activation signal and additional co-stimulatory signaling is needed. For example, chimeric CD28 and OX40 can be used with CD3-zeta to transmit a proliferative/survival signal, or all three can be used together.
