Daudi Cells
















Essential facts about Daudi cells
Description | The Daudi cell line was established in 1967 from a 16-year-old African boy diagnosed with Burkitt's Lymphoma, a type of lymphoma. Named after the patient from whom it was derived, the Daudi cell line is characterized by its Epstein-Barr Virus (EBV) positivity, a common feature in Burkitt's lymphoma and several other lymphoproliferative disorders. The EBV infection within these cells offers a unique model for studying the virus's role in tumorigenesis, particularly in the context of B-cell malignancies. Daudi human cells lack expression of the classical Major Histocompatibility Complex (MHC) class I molecules on their surface, which is attributed to the absence of beta-2-microglobulin, a crucial component responsible for the correct intracellular folding and processing of the MHC class I molecule in the endoplasmic reticulum. The lack of beta-2-microglobulin in the Daudi cell line leads to a lack of glycosyl modifications necessary for proper cell surface expression of these molecules. The Daudi cell line is extensively utilized in immunology research, particularly in studies involving the immunodepletion of lymphocyte subpopulations, including lymphocytes, natural killer cells, and peripheral blood mononuclear cells. In summary, the Daudi cell line serves as a critical resource for advancing our knowledge in various research fields, from the basic understanding of cell biology to the development of targeted therapies for cancer treatment. |

Required products
Initially designed to support the growth of human leukemic cells in both suspension and monolayer cultures, RPMI 1640 Medium has evolved through modifications by researchers and commercial suppliers to become suitable for a diverse range of mammalian cells. It is exceptionally compatible with cell lines such as HeLa, Jurkat, MCF-7, PC12, PBMC, astrocytes, and carcinomas.
RPMI 1640 Medium stands apart from other cell culture media due to its unique composition. It contains a substantial amount of phosphate, amino acids, and vitamins. Notably, it encompasses biotin, vitamin B12, and PABA, absent in Eagle's Minimal Essential Medium or Dulbecco's Modified Eagle Medium. Moreover, RPMI 1640 Medium exhibits significantly elevated concentrations of vitamins inositol and choline. However, it does not contain proteins, lipids, or growth factors. Consequently, supplementation with 10% Fetal Bovine Serum (FBS) is commonly required to provide optimal conditions for cell growth.
The buffering system of RPMI 1640 Medium relies on sodium bicarbonate and necessitates a 5-10% CO2 environment to maintain a physiologically appropriate pH. The inclusion of the reducing agent glutathione further distinguishes this medium from others.

Phosphate-buffered saline (PBS) is a widely used buffer solution in biological and chemical research. It plays a crucial role in maintaining the pH balance and osmolarity during various experimental procedures, including tissue processing and cell culture. Our PBS solution is meticulously formulated with high-purity ingredients to ensure stability and reliability in every experiment. The osmolarity and ion concentrations of our PBS closely mimic those of the human body, making it isotonic and non-toxic to most cells.
Composition of Our PBS Solution
Our PBS solution is a pH-adjusted blend of ultrapure-grade phosphate buffers and saline solutions. At a 1X working concentration, it contains:
8000 mg/L Sodium chloride (NaCl)
200 mg/L Potassium chloride (KCl)
1150 mg/L Sodium phosphate dibasic anhydrous (Na2HPO4)
200 mg/L Potassium phosphate monobasic anhydrous (KH2PO4)
This composition ensures an optimal pH and ionic balance, suitable for a wide range of biological applications.
Applications of Our PBS Solution
Our PBS solution is ideal for various applications in biological research. Its isotonic and non-toxic properties make it suitable for substance dilution and cell container rinsing. PBS solutions containing EDTA are effective for disengaging attached and clumped cells. However, divalent metals such as zinc should not be added to PBS, as this can cause precipitation. In such cases, Good's buffers are recommended. Additionally, our PBS solution is an acceptable alternative to viral transport medium for the transport and storage of RNA viruses, including SARS-CoV-2.
