In the field of viral immunology, the LCMV gp33 peptide has emerged as a foundational tool for researchers aiming to understand cellular recognition mechanisms. As someone who frequently works with synthetic peptides for in vitro experimental models, I have found that the precision of th Splenocytes from WT and RANTES−/−mice were stimulated withGP33and GP66peptidesto measure cytokine responses from CD8 and CD4 T cells, respectively (D–F).Read more ese sequences is vital for consistent results. Whether you are investigating the LCMV gp33–41 epitope or testing specific vari Data Sheet LCMV gp33 peptide KAVYNFATM ants, understanding the biochemical properties of this 9-aa-long pe In Vivo Selection of a Lymphocytic Choriomeningitis Virus ptide is essential for high-quality data.
Defining the LCMV gp33–41 Epitope
The LCMV gp33–41 sequence is a lymphocytic choreomeningitis virus (LCMV) glycoprotein segment that serves as a benchmark in immunological studies. This Class I MHC restricted epitope is widely recognized for being derived from the glycoprotein (GP33 peptide) of the virus.
When ordering this reagent, you will often see it listed as a single peptide (KAVYNFATM) for stimulation of murine LCMV gp33-spe gp-33 peptide GP33 - peptides707.info cific CD8+ T-cells. The standard KAVYNFATM sequence is the wild-type version, although some studies utilize the KAVYNFATC sequence, which also covers the 33-41 range and maintains high affinity for the H-2Db molecule.
Key Characteristics and Specifications
For those of us managing laboratory inventories, the quality of the peptide is paramount. Most reputable suppliers offer this peptide with a guaranteed purity of >70% or >95%.
* Sequence: KAVYNFATM (or KAVYNFATC for specific variants).
* Length: 9 amino acids.
* Restriction: H-2Db MHC Class I.
* Function: Acts as a critical component in the study of viral immunology.
In my experience, the LCMV GP33 CD8 epitope is remarkably stable when stored correctly at -20°C or -80°C in lyophilized form. It is frequently employed in assays involving GP33 peptide–treated mice or to calibrate LCMV-derived peptide responses in controlled settings.
Variations and Research Flexibility
The research community often explores modifications to the native sequence. For instance, the l- to d-amino acid substitution in the immunodominant LCMV-derived epitope gp33 has provided deep insights into how T-cell receptors (TCR) distinguish between subtle chemical changes.
Furthermore, when discussing GP(33-41), a 9-aa-long peptide, it is important to note its role in upregulating H-2Db molecules. Whether you are looking A Structural Basis for LCMV Immune Evasion: Subversion for a GP33 tetramer or a basic KAVYNFATC preparation, ensure that the source provides a clear certificate of analysis. I have found that even minor variations, such as those involving 43 residues or carboxyl-extended versions, can significantly alter binding kinetics.
Practical Considerations for Laboratory Use
When working with LCMV, specifically the gp 33 protein, consistency is your best asset. The LCMV gp33–41 H-2Db complex is the gold standard for studying T-cell GP(33-41), a 9-aa-long peptide, is the optimal sequence of the GP1 epitope of lymphocytic choriomeningitis virus, and can upregulate H-2Db molecules at the activation. If you are performing stimulation assays, ensure your LCMV gp33-41 is reconstituted according to the manufacturer's buffer recommendations to avoid aggregation.
The LCMV gp33 remains one of the most reliable antigens for those studying immune responses in a laboratory environment. By focusing on high-purity peptides and strictly following established protocols for GP33, researchers can continue to push the boundaries of our understanding of viral recognition without the need for complex, in-human variables. Always verify your sequence—whether KAVYNFATM or the C-peptide variant—to ensure it aligns with the specific parameters of your experimental design.
