I’d say this slowly:
Refuse to let anyone define you by single moments in your life, whether mistakes you made or victories you won. Accept that you are more than both.

Grad school can be challenging, so starting to read journals early & tracking your references can help reduce pressure. Building a community and staying involved is also important; finding balance is key to your well-being. Remember, you’re not alone🥰
It is that time of the year again 💃🏼💃🏼

Hi everyone,
I am Quadrat , a 4th Year Ph.D student @Olemiss where I am mapping Glycans topography using CF3 radical & Tandem Mass Spectrometry.
Glad to connect with y’all.
@sonsydarlin@OleMiss 8. Understanding the surface structure of glycans helps us:
a. Learn how viruses or bacteria stick to our cells.
b. Design better vaccines, diagnostic tools, or therapies.
•Discover new ways to target diseases that rely on sugar–protein interactions (like cancer )
@sonsydarlin@OleMiss Imagine Glycans as Trees and Proteins as Forests
1. Glycans are complex sugar chains found on the surface of cells, like branches and leaves sticking out from a tree.
2. These glycans help cells communicate, fight infection, and carry out many essential functions,
@sonsydarlin@OleMiss c. Then it analyzes the weight of each piece, allowing us to determine which pieces have the CF₃ tag and therefore were exposed.
d.With this information, we can reconstruct a 3D-like surface map of the glycan (what’s on the outside, what’s hidden, and what’s interacting).
@sonsydarlin@OleMiss 7. After the glycan is hit with CF₃ radicals:
a.Tandem Mass Spectrometry (MS/MS) is like a powerful scanner that can read exactly where the CF₃ paintballs landed.
b.First, it breaks the glycan into smaller pieces.
@sonsydarlin@OleMiss 3. But to really understand what glycans are doing, we need to map their surface: which parts are exposed, which are buried, and which interact with proteins. This surface map is what we call glycan topography.
@sonsydarlin@OleMiss 6. And we call the process of adding the CF3 “footprinting” : because the radicals leave marks where they hit, just like footprints in wet sand.
@sonsydarlin@OleMiss 5. CF₃ radicals are extremely reactive particles that randomly stick to exposed spots on the glycan.
If a spot is buried or shielded (perhaps by a protein), the paintball can’t hit it. So, wherever these radicals stick, we learn: “Aha! That part of the glycan is accessible.
