 Cell Cytotoxicity Assay Kit (Suspended Target Cells)

Cell Cytotoxicity is a critical quality attribute (CQA) for the biological activity of immune cell therapy products (e.g., NK cells, CAR-NK cells, Tm cells, CAR-T or TCR-T cells, etc.), and it is an important element of product quality research and quality control. Compared with cell cytotoxicity methods such as lactate dehydrogenase (LDH) assay, 51Cr release assay, luciferase reporter gene assay, RTCA assay, the detection of CFSE- and 7-AAD-labelled cell killing by flow cytometry is safer, more convenient, faster and more stable. To streamline your quality control workflow, we offer a specialized nk cell cytotoxicity assay kit optimized for this flow cytometry-based approach, ensuring precise and reproducible results.

 

Features of nk cell killing assay Kit (Suspended Target Cells)

01 Dual-Label Precision: CFSE labels target cells; 7-AAD identifies lysed cells.

02 High Throughput: Compatible with 96-well plates.

03 Safety: Eliminates radioactive isotopes (vs. 51Cr).

 

Application of ldh cytotoxicity detection kit (Suspended Target Cells)

It is suitable for the evaluation of the killing function of immune cell products such as NK cells, CAR-NK cells, CAR-T cells, TCR-T cells, Tm cells, etc. on different tumour cell lines (suspended target cells).

 

CMC and quality research phase: In the early development phase of cell therapy products, the cytotoxic effect is evaluated and the process is optimised.

 

Release testing, stability and comparability studies phase: During the mid-term process lock phase of cell therapy products, a cell killing method for the product is established, and release testing and stability testing of the cell product are performed.

HiPlas™ LentiHelper Plasmids for T

图片
  Compared with the three-plasmid vector system, the four-plasmid vector system greatly reduces the possibility of RCL production and increases the safety of the vector system. The third generation lentiviral packaging  platform contains four plasmids in the lentiviral packaging plasmids  system, including a shuttle plasmid containing exogenous target genes and three helper plasmids which include two packaging plasmids and one envelope plasmid, respectively.   The premade plasmid production  (HiPlas ™ lentihelper plasmid  for T) on the platform plasmid system for lentiviral packaging of CAR-T, TCR-T and other lentiviral plasmids  provided by Jiangsu Hillgene can meet the needs of customers at various stages of pre-clinical research, IIT, IND application, clinical trials and commercialization.   We can also provide kinds of plasmid extraction kit   for sale, if you are interested, please contact us.   For more information about hillgene b...
