Immunostaining Analysis of GOLM1 and FAM49B

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunostaining reactivity was observed using light microscopy (Olympus BX-53 with CCD DP74, Shinjuku, Japan). The results were analyzed by two pathologists (Xi Y and Chen H) who acted independently and were blind to the clinicopathological characteristics of the study. The analyses of the two pathologists were compared, and any discrepancies were reassessed to arrive at a consensus. The expressions of GOLM1 and FAM49B in tumor and immune cells were recorded for further research.

Immunostaining reactivity was observed using light microscopy (Olympus BX-53 with CCD DP74). Results were scored by two pathologists (Guo W and Chen H) who were independent and blinded to the clinicopathological characteristics of the study. The scores of the two pathologists were compared, and any discrepancies were reassessed to achieve a consensus.

Characterization of Nano-Sized Bubbles

Check if the same lab product or an alternative is used in the 5 most similar protocols
The morphology of NBAV was observed by scanning electron microscopy (SEM, S-4800, HITACHI, Japan) and the images were captured by software (HITACHI S-4800, PC-SEM). During the NBAV preparation, the lipid dye DiI (5 μM) was dissolved in the lipid solution for better observation. All other procedures remained the same. The obtained NBAV were examined under a fluorescence microscope (Olympus CKX53, Japan), and images were captured (Camera: Olympus CCD DP74).
The characterization of NBAV, such as size distribution, zeta potential, polydispersity index and stability of NBAV, were measured as described below. The diluted NBAV (4.5 ± 1.0×108 bubbles/mL) solutions were kept at 4 ℃, and then the size distribution was analyzed after 0, 12, 24, 36, 48, 60 and 72 h, respectively, by a NanoPlus-3 zeta/nano particle analyzer (Micromeritics Instrument CORP, USA). Furthermore, 1mL of NBAV stock solution was diluted with a 9 mL mixture of PBS (0.01 M) and fetal bovine serum (10%, FBS, HyClone, USA), and then size was measured after 0, 20, 40, 60, 80, 100 and 120 min at 37 ℃. The zeta potential of NBAV was also measured with this analyzer. All the experiments were repeated three times.

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.
