4T1-luc2: An Orthotopic Mammary Cancer Model to Support Novel Immuno-Oncology Drug Discovery

Breast cancer is the second most deadly malignancy after lung cancer in woman in the United States, with an estimated 246,000 new cases and 40,450 deaths expected in 2016. Many treatment options for breast cancer exist including surgery, radiotherapy, anti-estrogen therapy, targeted therapies (e.g., trastuzumab), and chemotherapy. Despite these therapeutic advances, metastatic disease remains a […]

Immune Profile of the Neuro-2a Mouse Neuroblastoma Model by Flow Cytometry

Neuroblastoma is an extracranial tumor that arises from neural crest-derived progenitor cells. It is the most prevalent solid tumor in childhood and the most common tumor in infants less than one year of age. With up to 800 new cases diagnosed each year, in spite of aggressive multi-modal therapeutic approaches, the 5-year survival rate in […]

5TGM1-luc – A Syngeneic Murine Model for Multiple Myeloma

Multiple myeloma is a malignancy of plasma B cells and is the second most common hematological malignancy in the United States. Malignant myeloma cells accumulate in the bone marrow and ultimately replace normal hematopoetic stem cells, which results in progressive leukocyte deficiencies. Chemotherapeutic agents and proteasome inhibitors are standard-of-care front […]

Flow Cytometry Based Functional Assays Essential for Characterizing Biological Significance

The efficacy of immune-modulating anti-cancer therapeutic antibodies that have been FDA-approved in recent years, such as anti-CTLA-4 and anti-PD-1, has driven growing interest in methods that provide a mechanistic understanding of drug function. Development of new mono and combination therapies with immune-modulatory effects requires more powerful immunophenotyping techniques capable of […]

In-Depth Myeloid Cell Characterization in the Murine Syngeneic CT.26 Colon Carcinoma Model by 10-Color Flow Cytometry

The efficacy of immune-modulating anti-cancer therapeutic antibodies that have been FDA-approved in recent years, such as anti-CTLA-4 and anti-PD-1, has driven growing interest in methods that provide a mechanistic understanding of drug function. Development of new mono- and combination therapies with immune-modulatory effects requires more powerful immunophenotyping techniques capable of in depth cell characterization. During […]

Evaluation of the Immune Response Following Treatment with Anti-CTLA-4 Antibody, Radiation Therapy, or the Combination in Murine Model of Breast Cancer

Breast cancers are considered poorly immunogenic tumors, however, several approaches utilizing immunotherapies are being undertaken in the clinic to evaluate their potential for improving outcomes. Radiation therapy (RT) is a highly utilized clinical treatment modality in breast cancer. Radiation is known to modify the tumor microenvironment, induce cytokines and chemokines, and has been shown to […]

CT26: Murine Colon Carcinoma

An estimated one in 20 people will develop colon cancer, making it one of the most frequently diagnosed cancers both in men and women. Due to improved screening methods, the overall incidence of colon cancer has declined during the past 20 years. However, it is still projected that only 40% […]

Get Glowing Results From Your Cell Lines – With Luciferase

Firefly (P. pyralis) luciferase is an enzyme that produces bioluminescence in the presence of D-luciferin. The DNA for the luciferase 2 (luc2) gene, along with a puromycin resistance gene, is incorporated into the genome of the cells using a lentiviral transduction system. While culturing the cells, puromycin is added to […]
