Measuring 5-HT and NE in Depression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Blood samples were collected both at RW and after SD, which were performed after the HAMD assessment and MRI scan. Because the procedure of blood sample collection was invasive, only 17 paired samples were finally obtained. Blood was collected into ethylenediaminetetraacetic acid tubes (5 ml, for measurement of 5-HT and NE). Samples were left standing at room temperature for at least 30 min. The supernatant serum was removed after centrifuging at 3,000 × g for 10 min in a 4°C centrifuge. Then, a 600-μl liquid component was immediately transferred in Eppendorf tubes, which were stored at a −80°C refrigerator until further use. Enzyme-linked immunosorbent assay was performed to measure the concentrations of 5-HT (Elabscience, E-EL-0033c, China) and NE (Elabscience, E-EL-0047c, China) following the manufacturer's instruction (27 (link)).

After removing myometrium, the endometrium at implantation sites on day 5 of pregnancy was homogenized for serotonin measurement according to the manufacturer’s instructions (Elabscience, E-EL-0033c, Wuhan, China). This kit’s sensitivity is greater than 9.38 ng/ml. The standard working solution or samples of 50 μL were mixed with 50 μL biotinylated antibody in working solution and incubated at 37° C for 45 min. Following washing 3 times, 100 μL HRP enzyme conjugate working solution was added to each well and incubated at 37° C for 30 min. After washing 5 times, 90 μL of substrate solution was added to each well and incubated at 37° C for 15 min. Absorbance at 450 nm wavelength was measured following adding 50 μL of termination solution to each well. Each experiment was repeated at least three times.

Enzyme-linked immunosorbent assay was applied to detect the serum levels of 5-HT (E-EL-0033c; Elabscience, Wuhan, Hubei, China) and NGF (EK1141-24; Mutiscience, Hangzhou, Zhejiang, China) according to the manufacturer’s protocol.

Serotonin Levels in ACC with Aerobic Exercise

Check if the same lab product or an alternative is used in the 5 most similar protocols
To investigate whether serotonin release was altered in the ACC with regular aerobic exercise training, serotonin levels in the ACC were tested by enzyme-linked immunosorbent assay. The levels of serotonin in the ACC were determined 15 d after regular aerobic exercise via enzyme-linked immunosorbent assay according to the manufacturer’s instructions. Briefly, the bilateral ACC was dissected from the brain and homogenized with ice-cold sterile 0.1 M PBS via ultrasonication. The supernatant was collected, and the amount of 5-HT in each sample was analyzed in duplicate using an enzyme-linked immunosorbent assay kit (E-EL-0033c, Elabscience, China).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
