稳定性测试
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.
-

Protein Description
VTG2, or vitellogenin 2, is a major yolk protein precursor found in various oviparous organisms, playing a crucial role in oocyte development and egg formation. Research on VTG2 has gained considerable attention due to its significance in reproductive biology and its potential applications in aquaculture and environmental monitoring. As a key component in the nutritional provisioning of developing embryos, VTG2 synthesis is tightly regulated by hormones such as estrogens, making it a valuable biomarker for assessing endocrine-disrupting chemicals in aquatic ecosystems. Furthermore, the study of VTG2 offers insights into evolutionary adaptations in reproductive strategies among different species, thus providing a comparative framework for understanding the molecular mechanisms underlying egg production. Advances in recombinant protein technologies have enabled the production of VTG2 in vitro, allowing for detailed investigations of its structure, function, and interactions with other molecular players during oogenesis. Overall, the exploration of VTG2 not only enhances our knowledge of reproductive physiology but also contributes to broader ecological and biotechnological applications, underscoring its significance in both basic and applied research contexts.
