Tagging and Fusion Proteins

Tagging and Fusion Proteins

Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from the other proteins in the cell. This is achieved by overexpressing the specific gene in a suitable host to produce large quantities of the target protein. A tag or label is recombined with the gene to produce a fusion protein containing the target protein and the tag. The tags on these fusion proteins can then be used for easy detection and...

Background:

Geant4 is a powerful Monte Carlo toolkit for radiation transport simulation.
Its steep learning curve presents a barrier for new users.
A need exists for simplified tools to facilitate Geant4 adoption.

Purpose of the Study:

Introduce M-TAG (Modular Radiation Teaching-Aid for Geant4), a user-code designed to ease Geant4 learning.
Simplify the integration of new geometries and detector components.
Validate M-TAG's effectiveness as a teaching aid and simulation tool.

Main Methods:

Developed M-TAG, a modular toolkit built upon Geant4.
Performed simulations to calculate positron ranges in water for isotopes F-18, C-11, O-15, and Ga-68.
An inexperienced user created a plastic scintillator detector model and performed dose calculations.
Compared simulation results with literature values and NIST XCOM data.

Main Results:

Positron travel distances and energy spectra means closely matched literature values.
Simulated dose ratios for a plastic scintillator detector agreed with NIST XCOM mass-attenuation ratios within uncertainties.
The new user successfully created and validated simulation models using M-TAG.

Conclusions:

M-TAG is a verified and effective modular teaching aid for Geant4.
It successfully simplifies complex radiation transport simulations for novice users.
M-TAG facilitates practical detector development tasks and validation studies.
