Ambient temperature directly affects the biochemical processes of organisms and is critical to the survival and proliferation of animals. Animals therefore employ a range of mechanisms to cope with environmental changes. Cold tolerance in C. elegans is a novel concept compared to heat tolerance and is responsible for different neurons and signaling pathways. At CD BioSciences, we provide C. elegans cold tolerance analysis services to help customers understand the mechanism of cold adaptation and advance experimental progress.
The growth rate and reproductive efficiency of many animals are affected by environmental changes. Most animals have evolved to cope with warming and cooling, developing mechanisms to adapt and tolerate temperature changes. Organisms adapt to changes in environmental temperature through a variety of mechanisms, or through endogenous homeostatic mechanisms, such as changes in fatty acid and phospholipid saturation of total lipids. C. elegans maintains cell membrane fluidity at low temperatures by increasing the overall proportion of saturated fatty acids. Temperature-sensing neurons (ASJ) of C. elegans detect temperature and control cold tolerance through insulin signaling.

C. elegans is suitable for cold tolerance research because of its simple nervous system, easy laboratory culture, and fast reproduction speed. In addition, C. elegans also exhibited morphological and behavioral changes in response to cold stress. Using C. elegans as a model, the behavior and mechanism of animal adaptation to environmental changes can be studied.
C. elegans is an attractive model to study cold tolerance, not only capable of responding to changes in environmental temperature by changing morphology and behavior, but its molecular genetics are well established. CD BioSciences focuses on providing cutting-edge services in the field of C. elegans research. With our professional knowledge and rich experience, we are confident to provide you with customized solutions for C. elegans cold tolerance analysis to advance your research progress. The following are the key elements of my C. elegans cold tolerance analysis service:
