All Gemini human sera is sourced from carefully screened donors
at FDA-licensed collection centers. These donors must pass strict
requirements for hematocrit, total protein, and must be in good
health. They are additionally tested for a number of diseases,
screened for ALT (alanine transaminase), found to be negative for
Indirect Coombs, and are found to be negative for all
FDA-approved viral markers. Gemini offers an extensive line of
human serum and plasma products.
Gemini’s extensive line of animal serum products are stringently
quality controlled prior to release for sale. Tests include
biochemical profile, sterility, mycoplasma, virus screening, and
endotoxin. Gemini Bio-Products animal sera has been collected
from inside the continental United States, or from countries
approved for importation by the USDA.
Gemini’s mLIF (Leukemia Inhibitory Factor – mouse) is a lymphoid
factor which is utilized in a number of reproductive,
inflammatory, developmental and regenerative processes. LIF is
commonly used to enhance proliferation and growth of ES cells
while inhibiting cellular differentiation. Gemini derives its LIF
through engineered cell lines.
Gemini manufactures a high-quality line of specialized liquid and
powder media products. These products are designed to
promote cell growth in both a serum supplemented and a serum-free
environment. The products include easy-to-use media
intended for use in t-cells, long-term culture of embyronic
hippocamal neurons, and insect cell growth. Each product is
available in a number of options.
ITS (Insulin, Transferrin, Selenium) is a chemically defined
supplement for a variety of cell culture applications. ITS
supplement contains components which are required for optimal
performance of serum-free media. Supplementation of ITS to
different conventional nutrient media substantially reduces the
FBS requirement for routine maintenance of many cell lines.
Components: Contains 1.0 mg/ml insulin from bovine pancreas, 0.55
mg/ml human transferrin (substantially iron-free), and 0.5 µg/ml
