Get 6 Complimentary Germ-Free Mice for Your First GF Experience with GemPharmatech

May 01,2023

Germ-free (GF) mice are laboratory animals that have no detectable living organisms (including microorganisms or parasites). Compared to conventional SPF animals, GF animals require more rigorous control of microorganisms, and the maintenance of GF status is technically more challenging.

Characteristics of GF Mice

1. Lower body weight and reduced weight of the heart, liver, kidney and spleen;

2. Weaker digestion and absorption function, thinner intestinal muscle layer, increased intestinal villi and enlarged cecum;

3. Weaker immune system function, with a significant decrease in the concentration of lgA in the blood.

Application of GF Mice

GF animals have been extensively use in a wide range of research:

a. Host-Microbe interaction

b. Disease causality and pathogenesis

c. Animal husbandry and animal nutrition

d. Drug efficacy evaluation and safety assessment

e. Probiotics, prebiotics and live biotherapeutics

f. Cancer immunotherapy

g. Metabolic diseases

h. Autoimmune diseases

i. Neurological disorders
