Predicted Structure And Analysis Of The Glycoprotein From Sars-Cov-2 Variants Of Interest, Boris Shabaltiy Oct 2023

Predicted Structure And Analysis Of The Glycoprotein From Sars-Cov-2 Variants Of Interest, Boris Shabaltiy

Honors Theses

SARS-CoV-2 has had a devastating effect on the world, and while the public concern and severity of the diseased caused by it have decreased, it is still crucial to monitor the virus for mutations so we can rapidly identify new variants of concern, and then rapidly prepare new vaccines and treatments. The SARS-CoV-2 spike (S) protein from the first isolates of the virus (root variant) was structurally characterized in early 2021. The spike protein structure, designated 7CZW, was uploaded to RCSB Protein Data Bank (RCSB PDB). All subsequent mutations the S protein has accumulated are based on the amino acid …


Development Of Recombinant Varicella-Zoster Virus Vaccines Expressing Sars-Cov-2 Antigens, Cody Wilson May 2023

Development Of Recombinant Varicella-Zoster Virus Vaccines Expressing Sars-Cov-2 Antigens, Cody Wilson

Honors Theses

The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2) continues to cause infections and deaths around the globe. Since its emergence, scientists have worked diligently to discover and produce vaccines to battle the virus. While they successfully created and distributed vaccines, the vaccines are not without flaw. These vaccines do not grant long term immunity, require multiple booster shots, and have not prevented the emergence of viral variants. In this study, the SARS-CoV-2 receptor binding domain (RBD), which is a key part of the spike protein (S), and nucleocapsid (N) genetic sequences were inserted into the live varicella …


Implications Of Antibiotic And Bacteriophage Resistance In Environmentally Isolated E. Coli, Michael Connolly Jun 2022

Implications Of Antibiotic And Bacteriophage Resistance In Environmentally Isolated E. Coli, Michael Connolly

Honors Theses

The increasing prevalence of antibiotic-resistant bacteria is an emerging problem for humans. Clinical misuse, overuse in agricultural and food settings, and limited numbers of new antibiotics have accelerated the proliferation of antibiotic-resistant bacteria. To confront this threat, scientists must develop new therapeutics that kill these antibiotic-resistant bacteria. In this study, we used Escherichia coli to analyze antibiotic and bacteriophage susceptibility. E. coli is a common, mostly benign, enteric, gram-negative bacteria. We isolated three E. coli strains from the Hans Groot Kill, a stream that runs through Union College’s campus. We sought to assess various E. coli strains’ antibiotic resistance, susceptibility …


Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara May 2020

Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara

Honors Theses

Described as one of the world’s worst pandemics, HIV (Human Immunodeficiency Virus) infects millions of people each year and is the cause for AIDS (Acquired Immunodeficiency Syndrome). Despite the development of vaccines for numerous infectious diseases such as polio, small pox, and influenza, a vaccine for HIV remains elusive due to the virus’s high mutation rate and ability to evade the immune system. HIV causes depletion of CD4+ lymphocytes, resulting in a weakened immune system. However, the development of a plasmid-based DNA vaccine approach may help revolutionize vaccine development for HIV due to its ability to confer cellular and humoral …


Genetic Diversity Of Potassium Ion Channel Proteins Encoded By Chloroviruses That Infect Chlorella Heliozoae, Carter Murry Mar 2020

Genetic Diversity Of Potassium Ion Channel Proteins Encoded By Chloroviruses That Infect Chlorella Heliozoae, Carter Murry

Honors Theses

Chloroviruses are large, plaque-forming, double-stranded DNA viruses that infect chlorella-like green algae that live in a symbiotic relationship with protists. Chloroviruses have a genome from 290 to 370 kb, and they encode as many as 400 proteins. One interesting feature of chloroviruses is that they encode a potassium ion (K+) channel protein named Kcv. K+ channels are essential proteins for life. They cross the membrane of the cell to quickly and selectively allow K+ in or out of the cell. This helps regulate the electrical charge of a cell which in turn helps control electrical signaling …


Production Of Antibodies For Specific Detection Of Dengue Virus-2 By Surface Enhanced Raman Spectroscopy, E. Ashley Thompson May 2017

Production Of Antibodies For Specific Detection Of Dengue Virus-2 By Surface Enhanced Raman Spectroscopy, E. Ashley Thompson

Honors Theses

Dengue Virus (DENV) is a flavivirus spread by mosquitoes that are endemic in tropic and subtropic climates. It is the causative pathogen of Dengue Fever, Dengue Hemorrhagic Fever, and Dengue Shock Syndrome. Besides mosquito transmission, DENV can also be transmitted through blood transfusion. Due to the high expense and expertise needed to run tests like ELISA and Polymerase Chain Reaction (PCR) based-assays for DENV detection, a rapid, sensitive and cost effective gold nanoparticles mediated surface-enhanced Raman spectroscopy (SERS) assay has been developed as an alternative assay to detect DENV. In this project, I successfully produced a monoclonal antibody that specifically …
