Human Interleukin-2 (IL-2) ELISA Kit: Sample Collection and Storage Guidelines Before collecting samples for IL-2 testing, it's important to confirm that the target analytes are stable under the intended storage conditions. If the samples will be tested on the same day they are collected, store them at 4Â°C for short-term use. For longer storage or if testing is delayed, it's recommended to collect samples in aliquots and store them at -20Â°C or -70Â°C. Repeated freeze-thaw cycles should be avoided to prevent degradation of the cytokine. Under proper conditions, samples can be stored for up to 48 hours at 2â€“8Â°C, one month at -20Â°C, and six months at -70Â°C. Some hormone-containing samples may require the addition of a protease inhibitor like aprotinin to maintain stability and prevent protein breakdown during storage. Always follow the manufacturerâ€™s instructions for optimal results and ensure all procedures are performed under sterile conditions to avoid contamination. Proper labeling of each sample with collection date and time is also essential for accurate data interpretation.
