生物活性

重组人白介素2(Recombinant Human IL-2)可以使活化的T细胞在体外培养中长期持续增殖。静止的T细胞表面不表达IL-2R,对IL-2没有反应;受丝裂原或其它刺激活化后T细胞才能表达IL-2R,成为IL-2的靶细胞。NK细胞是唯一正常情况下表达IL-2R的淋巴样细胞,因此始终对IL-2保持反应性。然而静止的NK细胞上只表达IL-2R的β链和γ链,对IL-2的亲和力低,只能对高浓度的IL-2发生反应。一旦NK细胞活化,就表达IL-2R的α链,成为高亲和力的受体。

通过用 CTLL-2 细胞进行细胞增殖测定,该效应的生物学活性为 2×107IU/mg。


预测的理论分子量为 15.4kD

Endotoxin < 0.1 EU/μg

Recombinant Human IL-10 (CHO)

Interleukin-10 (IL-10) is usually secreted as a homodimer and, upon binding to its receptor, inhibits the synthesis of a number of cytokines, including IFN-gamma, IL-2, IL-3, TNF and GM-CSF produced by activated macrophages and Th2 cells.

Recombinant Human IL-5 (CHO)

Interleukin-5 (IL-5) is responsible for the activities attributed to eosinophil differentiating factor, B cell growth factor II and T cell-replacing factor (TRF). IL-5 plays an important role in inducing cell-mediated immunity against parasitic infections and certain tumors.

Recombinant Human Tau-F Protein (E.coli)

Tau proteins are proteins which contain four Tau/MAP repeats. They promote microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity.

Recombinant Human Tau Protein (E. coli, His Tag)

Tau proteins are proteins that stabilize microtubules. Tau protein is a highly soluble microtubule-associated protein (MAP). In humans, these proteins are mostly found in neurons compared to non-neuronal cells. One of tau's main functions is to modulate the stability of axonal microtubules.

Recombinant Rat IL-23 Protein (HEK293, C-His)

IL-23 (IL-23 alpha & IL-12 beta Heterodimer) Protein is a recombinant protein dimer complex containing rat-derived IL-23 alpha & IL-12 beta Heterodimer protein, expressed by HEK293.
