Stereotaxic frame at 45

Manufactured by Kopf Instruments
Sourced in United States

The Stereotaxic frame at 45° is a laboratory instrument used for precise positioning and immobilization of small animals, such as rodents, during surgical or experimental procedures. The frame is designed to hold the animal's head at a 45-degree angle, allowing for targeted access to specific brain regions. The core function of this device is to provide a stable, reproducible, and standardized platform for conducting research and procedures that require precise positioning and orientation of the subject.

The TBI was performed based on the previously reported procedures with modifications43 (link). Briefly, the benchmark stereotaxic impactor was mounted on a stereotaxic frame at 45° (David Kopf Instruments, Tujunga, CA, USA). Anesthetized mice were placed on a customized foam mold in prone position. To induce TBI, the tip was driven towards mouse head at a speed of 4.0–4.5 mm/s, a dwell time of 0.2 s set by the electronic control box and an impact depth of 3 mm adjusted by the stereotaxic device. After 2 h recovery, 4–6-week-old C57BL/6 was intravenously injected with 200 μL anti-CD11b-PEGylated PbS/CdS CSQD (O.D. = 0.5 at 808 nm) and monitored by wide-field system and oblique NIR-II LSM mounted with a 5X illumination objective and a 10X imaging objective 24 h post injection. The Z scanning increment, exposure time and excitation and emission wavelengths were summarized in Supplementary Table 2.

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.
