Wistar Rat Neurochemical Profiling

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experimental protocol was approved by the Animal Ethical Committee of No.4
People’s Hospital of Hengshui, Ethic No. HB2020-11(05). All experiments were
conducted as per the ethical guidelines of the Animal Ethical Committee.
Male Wistar albino rats were employed for the current study and were kept in the
animal house of People’s Hospital of Hengshui. The animals were provided with
standard feed and water. The animals were exposed to 12 h of light and 12 h of
the dark at 25 ± 2 °C and 55–60% relative humidity. The ELISA kits for the
quantification of BDNF (ab213899), TNF-α (ab236712) and Nrf2 (ab207223) were
procured from Abcam, USA. The ELISA kit for CSE (abx155408) was procured from
Abbexa LLC, Houston, USA; while the fluorometric assay kit for CBS (K-998) was
obtained from BioVision, Inc, California USA. Octreotide and ANA-12 were
procured from Sigma-Aldrich, USA.

Cardiac and Inflammatory Biomarkers in Rats

Check if the same lab product or an alternative is used in the 5 most similar protocols
On week 8, the body and hearts of the rats were weighed. Then, the rats were sedated through intraperitoneal injection of pentobarbital (1%). The blood specimens were harvested from the cardiac apex of rats, put into 2.0 mL heparinized Eppendorf (EP) tubes, mixed completely, and centrifuged at 8000 r/min and 4 °C for 6 min. The supernatant was stored at −80 °C. The creatine phosphokinase-MB (CK-MB) kit (H197-1-1, NanJing JianCheng Bioengineering Institute, Nanjing, China) was utilized to detect CK-MB levels. Sarcosine oxidase and urease methods were employed to measure blood creatinine (ab65340, Abcam, Cambridge, UK) and blood urea nitrogen (BUN; ab83362, Abcam), respectively. Inflammatory cytokines, interleukin-6 [(IL-6), ab234570], tumor necrosis factor-alpha [(TNF-α), ab236712], and interleukin-1 beta [(IL-1β), ab255730] were tested by corresponding enzyme-linked immunosorbent assay (ELISA) kits (Abcam). The above relevant biochemical indexes were measured strictly as per the specific operation steps and precautions of the corresponding kits, and the absorbance was calculated on a microplate reader. The sample concentration was calculated according to the formula or the standard curve regression equation corresponding to the biochemical indexes.

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.
