Clinical cell therapy: Mizumachi General Hospital, New City Osaki Hospital, and several top tier hospitals in China have all used it for in vitro expansion of CAR-T, CIK, and NK cell therapy, and its safety and effectiveness have been clinically validated;

Scientific research experiments: widely used in scientific research scenarios such as T cell activation, naive T cell enrichment, and immune cell function studies, it is the preferred culture medium for immune cell research;

Cell preparation: Combined with RetroNectin (recombinant human fibronectin fragment), it can further improve cell expansion efficiency, increasing the proportion of initial T cells by more than 40%.

The GT-T551 culture medium supplied by Huayi Sichuang Biotechnology can be directly used in all the above scenarios without additional pretreatment, saving experimental and preparation time.

Q3: What is the difference between GT-T551 and GT-T551H3, and how should I choose?

A: Both are TAKARA serum-free immune cell culture media, supplied synchronously by Huayi Sichuang Biotechnology in stock. The core difference lies in the buffer system and culture characteristics. Specific comparison and selection suggestions are as follows (data can be provided for original COA verification):

Selection suggestion: For routine immune cell culture and scientific research experiments, choose GT-T551; For clinical needs such as high proportion of initial T cells, plasma free culture, or CAR-T/NK cell preparation, GT-T551H3 is preferred. Both products from Huayi Sichuang Biotechnology are in stock and support small batch trial purchases.

Q4: What are the usage methods and precautions for GT-T551 culture medium?

A: To ensure the effectiveness of the training, Huayaisi Creative Biotechnology provides exclusive technical support and, in accordance with the original factory standard process, has compiled the following directly applicable usage methods and precautions. All operations have been validated in clinical and scientific research scenarios:

Standard usage process

Culture medium pretreatment: Remove the GT-T551 culture medium from the 2-8 ℃ freezer and thaw it. After thawing, gently invert and mix well. Before use, add 0.2% -0.3% human serum albumin as needed (if 0.6% autologous plasma is added, no additional albumin is required);

Cell inoculation: The initial inoculation density of T cells is controlled at 0.5-1 × 10 ^ 6 cells/mL, and Anti-CD3 monoclonal antibody (50-100 ng/mL)+IL-2 (300-500 IU/mL) is added to promote T cell activation;

Cultivation and harvesting: Cultivate in a 37 ℃, 5% CO ₂ incubator, add an equal amount of culture medium on the 3rd to 4th day, and harvest cells on the 7th to 10th day. At this time, the cell expansion factor can reach 3-5 times, and the cell viability is ≥ 90%.

Precautions

Storage requirements: Strictly store in refrigeration at 2-8 ℃, avoid repeated freezing and thawing, and avoid direct sunlight, otherwise it will affect the stability of the culture medium;

Quality control guarantee: Each batch of GT-T551 culture medium provided by Huayi Sichuang Biotechnology comes with TAKARA original COA quality inspection report, and key parameters such as endotoxins and sterility can be checked and verified;

Optimization suggestion: Combining RetroNectin coated culture bottles/bags can further improve T cell expansion efficiency and initial T cell ratio, adapting to culture requirements.
