NK and TIL Cell Expansion Reagents (K562 Feeder Cells)

 

NK and TIL Cell Expansion Reagents (K562 Feeder Cells)

Hillgene's NK and TIL Cell Expansion Reagent (Feeder cell) is an irradiated and inactivated engineered k562 cells expressing IL-21 and other cytokines, which, together with the mainstream immune cell culture medium, can activate and expand NK cells and tumor-infiltrating TIL cells derived from umbilical cord blood and peripheral blood mononuclear cells cultured in vitro, and the purity of the obtained NK and TIL cells is high.

Application of NK and TIL Cell Expansion Reagents (K562 Feeder Cell)

Suitable for activation and mass expansion of different immune cells such as NK cells, CAR-NK cells and TIL.

 

Process Development Stage: Evaluate the in vitro expansion capacity of cells such as NK and TIL and optimize the process during the early development stage of cell therapy products.

 

Process locking, product production and comparability study phase: During the mid-term process locking, production and cell process change phase after IND approval for cell therapy products, establish stable cell expansion processes based on trophoblast cells, such as NK and TIL, and carry out process locking, cellular drug production and comparability studies for cell products.

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...

  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 plat...
