Description

Application

Each vial contains >1X10⁶ viable cells.

Cells are tested negative for infectious diseases by a Mouse Essential CLEAR Panel by Charles River Animal Diagnostic Services.

Cells are negative for mycoplasma contamination.

The OSUMMER (Ohio State University and Moffitt Melanoma Exposed to Radiation) cell lines fill a previously unfilled gap in melanoma biology. The OSUMMER cell lines are syngeneic to C57BL/6 laboratory mice and have genetic profiles that are similar to human tumors, making them responsive to immunotherapy treatments. These NRAS-Mutant cell lines can be used to discover and address potential immunotherapies in NRAS-mutant human melanomas which make up an estimated 15-25% of human melanomas. These cell lines also enable in vivo testing of immunotherapies with a mouse model.

OSUMMER.2 NRAS mouse melanoma cell line was derived from a female TN mouse exposed to UVA and UVB radiation. OSUMMER.2 carries the specific NRAS mutation Q61R and can form tumors in vivo without Matrigel injection. WES revealed high SNV (Single Nucleotide variants) and low CNA (Copy Number Alterations) burden, as well as the presence of UV signature mutations. OSUMMER.2 cells express the melanoma markers PMEL and MelanA and exhibit robust growth in culture.

Source
OSUMMER.2 was derived from melanoma induced in TN (Tyr::CreER) mice exposed to UVA or UVB radiation on postnatal day 3 (1).

Features and Benefits

OSUMMER.2 carries the specific NRAS mutation Q61R and may be used to create syngeneic mouse melanoma models.

Storage and Stability

The cells should be stored in liquid nitrogen. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.
