Cell Line Description:
Nb2-11 is a clone of the Nb-2 rat lymphoma line which was derived from a transplant of a lymphoma that developed in the thymus/lymph node of a male noble (Nb) strain rat following prolonged oestrogen treatment. The cells are of the pre-T cell origin and their proliferation is dependent on mammalian lactogens, such as prolactin. Nb2-11 can also be mitogenically stimulated by IL-2. Injection of Nb2 cells into Nb rats gives rise to malignant tumours that are highly sensitive to treatment with vinca alkaloids. Karyotypic analysis has shown that the cell line has only five well developed chromosome abnormalities. The cells do not express surface immunoglobulin, and their lactogen dependency was confirmed before deposit. Protocols for the use of Nb2-11 cells in bioassays are available from ECACC on request.
Unless specified otherwise, at the European Collection of Authenticated Cell Cultures (ECACC) we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines. ACDP = Advisory Committee on Dangerous Pathogens (UK) All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country.
At resuscitation seed cultures at 3-5 x 100,000 cells/ml. Once established cultures should be seeded at 4x1,000 and 12x1,000 cells/ml for culture periods of 96 and 72 hours respectively. Incubate flasks at 37°C; 5 % CO2. Check daily. Do not exceed 9x100,000 cells/ml. Avoid using dilutions of cells with fresh medium at greater than 1:10 ratios; culture doubling time 12 hours.
Culture Medium:
Fischer's medium (Life Technologies product number : 21475025) + 10%Foetal Bovine Serum (FBS) + 10% Horse Serum (HS) (gelding) + 0.075% Na Bicarbonate + 0.05mM 2-Mercaptoethanol (2ME) + 2mM Glutamine.
