简介
HHLA2 protein, a key immune regulator, interacts with TMIGD2, providing crucial costimulation for T-cells during TCR-mediated activation. This interaction amplifies T-cell proliferation and cytokine production through an AKT-dependent signaling cascade, revealing HHLA2's role in enhancing T-cell responses and immune modulation. HHLA2 Protein, Human (Biotinylated, HEK293, Fc-Avi) is the recombinant human-derived HHLA2 protein, expressed by HEK293 , with C-Avi, C-hFc labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life

Protein Description
HHLA2 (Human High-Loading Immunoglobulin-like Protein 2) is a member of the B7 family of immune checkpoint molecules that has garnered significant attention in cancer research due to its role in modulating immune responses. Discovered as a novel co-stimulatory molecule, HHLA2 interacts with receptors on T cells, influencing their activation and function. Unlike its better-known counterparts such as PD-1 and CTLA-4, HHLA2's specific mechanisms and impacts on cancer progression are still being elucidated. Its expression is associated with various malignancies, where it may contribute to tumor immune evasion. The production of recombinant HHLA2 protein allows for in-depth studies of its structural characteristics, binding affinities, and functional interactions with T cell receptors. This research is vital for understanding how HHLA2 can be targeted for therapeutic purposes, particularly in the development of cancer immunotherapies. By examining the potential of HHLA2 as a biomarker for tumor progression and a target for immune modulation, researchers aim to create strategies that enhance anti-tumor immunity and improve patient outcomes.
