CST1, or cystatin SN, is a human gene encoding a secreted protein belonging to the type 2 cystatin superfamily, which includes CST1, CST2, CST3, CST4 and CST5. These proteins are cysteine proteinase inhibitors found in various human fluids and secretions where they appear to have protective functions. CST1 is specifically found in saliva, tears, urine and seminal fluid and plays a role in inhibiting the activity of cysteine proteases. CST1 has been implicated in several pathological processes, including tumour invasion and metastasis. Properties Storage Instructions All the reagents are stored at 2-8℃ for 6 months or -20℃ for 12 months. Refer to the protocol for further storage instructions.

Answer: We recommend performing a serial dilution. For example, if human serum requires a 1,000,000-fold dilution, you can use a three-step 100× dilution method as follows: Step 1: Take 2 uL of human serum and add it to 198 uL of sample diluent, mix thoroughly to obtain a 100-fold diluted sample. Step 2: Take 2 uL of the 100-fold diluted sample and add it to 198 uL of sample diluent, mix thoroughly to obtain a 10,000-fold diluted sample. Step 3: Take 2 uL of the 10,000-fold diluted sample and add it to 198 uL of sample diluent, mix thoroughly to obtain a 1,000,000-fold diluted sample. If further dilution is required, additional serial steps can be used. We do not recommend using any other solutions or water for dilution, except for the sample diluent we suggest. If your sample diluent is still insufficient, please contact our customer service for more sample diluent.
