KDEL

KDEL is a tetrapeptide serving as an endoplasmic reticulum (ER) retrieval/retention signal. KDEL can target and deliver exogenous antigen peptides to the ER, significantly enhance and prolong MHC class I molecule presentation, and effectively boost anti-tumor immune responses.

In Vitro

KDEL (10 μM; 30 min-10 h) fused to the C-terminus of OVA_257-264 enhances MHC class I-associated peptide presentation on EL-4 and RMA cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

KDEL (10 μM; subcutaneous injection after DC loading; twice) significantly enhances and prolongs MHC class I presentation of exogenous peptides in C57BL/6 mice, induces a stronger specific CTL response, and significantly inhibits E.G7‑OVA tumor growth^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

C57BL/6 mice (6-8 weeks old) with E.G7‑OVA tumor challenge^[1]
Dosage:

10 μM OVA_257‑264‑KDEL peptide
Administration:

subcutaneous injection ( days 0 and 7)
Result:

Induced greatly enhanced specific CD8⁺ cytotoxic T lymphocyte (CTL) responses, remarkably prolonged surface MHC class I/peptide complex display, and resulted in significant inhibition of E.G7‑OVA tumor growth in vivo compared with OVA_257‑264 or OVA_257‑264‑TEWT peptide groups.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
