BioVector® MUTU-III Cell Line
1. Background and Origin
MUTU-III (also designated as MUTU 3 or Mutu-3) is a human B-cell line derived from an endemic Epstein-Barr virus (EBV)-positive Burkitt lymphoma (BL).
The MUTU cell line family was established by serial passaging of the parental clone MUTU-BL, isolated from a biopsy of a male patient carrying the classic
2. Biological Characteristics
Taxonomy & Source: Homo sapiens, B lymphocyte, Burkitt lymphoma
Biosafety Level: BSL-2 (EBV positive; presents potential lytic activity and viral transmission risks during manipulation)
Growth Properties: Suspension; grows in clusters or single cells with background cell debris
Phenotypic & Marker Features:
Surface Antigens: CD19(+), CD20(+), CD37(+), CD38(+), CD80(+), HLA-DR(+), cyCD79a(+)
Genetics: Translocation $t(8;14)$; heterozygous mutation in MYC (p.Thr73Asn)
Viral Status: EBV(+) (Latency Type III, high EBNA2 & LMP1 expression)
Primary Applications: EBV latency/lytic cycle regulation, LMP1/EBNA2 signal transduction, lymphoma immunotherapy target validation, antiviral drug screening
3. Culture and Handling Protocols
Recommended Growth Medium
Base Medium: RPMI-1640
Supplements: 10% to 20% heat-inactivated Fetal Bovine Serum (FBS)
Culture Conditions: 37 degrees Celsius, 5% $CO_2$, humidified incubator
Thawing and Subculture Protocol
Thawing: Thaw the frozen vial rapidly in a 37 degrees Celsius water bath.
Transfer contents into 8–10 mL pre-warmed complete medium and centrifuge at 125 x g for 5 minutes. Resuspend in fresh medium and seed at $\ge 0.5 \times 10^6\text{ cells/mL}$. Subculturing:
Maintain working cell density between
$0.3 - 0.5 \times 10^6\text{ cells/mL}$. Split cells 1:2 to 1:3 every 2–3 days by adding fresh medium.
Do not allow density to exceed
$1.0 \times 10^6\text{ cells/mL}$.
Cryopreservation
