Cortisol Measurement in Zebrafish

Check if the same lab product or an alternative is used in the 5 most similar protocols
In view of the circadian rhythms, zebrafish were anesthetized with MS-222 at 9:00 am. For 6 dpf larval zebrafish, a pool of 30 larvae were homogenized in 500 μl cold PBS and then homogenized. At least eight 30-fish pools of each genotype were measured. Plasma was collected from 150 dpf zebrafish. The cortisol content was measured with a cortisol express EIA kit (Item No. 500370) from Cayman Chemical Company following the procedure provided by the manufacturer.

Quantifying Plasma Hormones: Leptin, Cortisol, and Insulin

Check if the same lab product or an alternative is used in the 5 most similar protocols
Plasma concentrations of leptin were determined by a multi-species leptin RIA kit (XL-85K, Millipore, Molsheim, France). The limit of sensitivity of the assay was 2 ng·mL−1 and the inter- and intra-assay coefficients of variance were <9 and <4%, respectively.
Plasma concentrations of cortisol were determined by a Cortisol Express EIA Kit (AYN830, Cayman Chemical, Ann Arbor, MI, USA). The limit of sensitivity of the assay was 0.1 ng·mL−1, while the coefficients of variance for a dose of 5 ng were equal, respectively, to 11 and 6% for inter- and intra-assays. Plasma levels of insulin were assayed with Ultra Rat Insulin ELISA Kit (# 90060, Crystal Chem, Downers Grove, IL, USA) using hamster insulin standard (# 90330, Crystal Chem) following the instructions of the manufacturer. The limit of sensitivity of the assay was 0.1 ng·mL−1 and the coefficients of variance were <10% for both inter- and intra-assays.

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.
