Iα52 is a naturally processed peptide encompassed the residues 52-68 of the murine I-Eα chain and may contribute to selection of immature T cells.

Insulin β Chain Peptide (15-23) is one of the earliest antigenic epitopes to which CD8 T-cells respond.

CFP10 (71–85) is a biological active peptide. (CFP1071–85, that elicited IFN-γ production and CTL activity by both CD4+ and CD8+ T cells from persons expressing multiple MHC class II and class I molecules)

SmBiT Tag is an 11-amino-acid short peptide with extremely low natural affinity for LgBiT, with a K_d value of approximately 190 μM. It serves as a core component of the NanoLuc Binary Technology (NanoBiT) system. NanoBiT is a bioluminescent reporter system based on protein fragment complementation technology, which is used to monitor dynamic protein-protein interactions in live cells and in vitro.

Dby HY Peptide (608-622), mouse is a biological active peptide. (Dby HY Peptide, NAGFNSNRANSSRSS, is a HYAb epitope belonging to a well-conserved family of genes coding for known or putative RNA helicases and containing a core sequence with a DEAD (Asp-Glu-Ala-Asp) box peptide motif, hence the name Dby (Dead box RNA helicase Y). The single Phenylalanine in the sequence serves as the anchor point while FNSNRANSS most likely is the “core” sequence of this HYAb epitope.)

G280-9 is a 9 amino acid native epitope peptide. G280-9 is a relevant target expressed on melanoma.

IGRP(206-214) is a biological active peptide. IGRP(206-214) corresponds to residues 206-214 of murine islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP). IGRP(206-214) is T cells specific for proinsulin and IGRP induces diabetes in non-obese diabetic (NOD) mice.

LMP2A (426-434) is a HLA-A2-restricted cytotoxic T lymphocyte (CTL) epitope of Epstein-Barr virus (EBV) latent membrane protein 2A (LMP2A). LMP2A (426-434) can trigger an immune response in individuals expressing different HLA-A*02 subtypes (A*02:01, A*02:03, A*02:06 and A*02:07). LMP2A (426-434) can induce a strong IFN-γ secretion response, stimulating the production of a high proportion of CD8⁺ IFN-γ⁺ T cells. LMP2A (426-434) induces specific CTLs to effectively kill target cells expressing LMP2A. LMP2A (426-434) can be used to study EBV-related malignant tumors (such as Hodgkin's disease and nasopharyngeal carcinoma) .

CMV pp65 (415-429) is a CEF control peptide that is derived from the Cytomegalovirus (CMV).

SIIVFEKL TFA is a variant of the major MHC class I-restricted epitope SIINFEKL. SIIVFEKL TFA is an antigenic peptide, that can stimulate specific T cells in experimental settings to study the competitive interaction between T cells. SIIVFEKL TFA exhibits low affinity for the OT-I T cell receptor (TCR), and can be used for detection of CD8+ T cells.

BDC2.5 mimotope is a potent antigen-mimicking peptide that can activate CD4+ T cell populations that have the same antigen recognition properties as BDC2.5 cells. BDC2.5 mimotope can be used to study the prevention or treatment of type 1 diabetes by targeting specific T cell populations.

CMV pp65(13-27) is a biological active peptide. (This peptide is derived from amino acid residues 13 to 27 of the 65k lower matrix phosphoprotein of the human cytomegalovirus. It contains a nine-amino-acid sequence (LGPISGHVL) that matches the consensus binding motif for a major histocompatibility complex H2-Dd T-cell epitope.)

EGFRvIII peptide (PEPvIII) TFA is a tumor-specific mutation that is widely expressed in glioblastoma multiforme (GBM) and other neoplasms and its expression enhances tumorigenicity. EGFRvIII peptide TFA represents a truly tumor-specific target for antitumor immunotherapy.

H-Gly-Leu-Phe-OH (GLF), an immunostimulatory tripeptide derived from α-lactalbumin, inhibits anticancer agent Etoposide-induced alopecia, epidermal thickening, and thinning of the adipocyte layer.

CKS-17 is a synthetic retroviral envelope peptide. CKS-17 has the highly conserved amino acid sequences occurring within the transmembrane envelope protein of many animal and human retroviruses. CKS-17 acts as an immunomodulatory epitope and exhibits suppressive properties for numerous immune functions.
