Validation Data Gallery：

	Purity of recombinant human IL-7 was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.
	Recombinant human IL-7 (HZ-1281) stimulates dose-dependent proliferation of the 2E8 murine B Lymphocyte cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. 2E8 cells were treated with increasing concentrations of recombinant IL-7 for 120 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.1-1.4 ng/mL.
	Proteintech IL-7 (HZ-1281) demonstrates 3-fold lower EC50 and equivalent induction of proliferation compared to a leading competitor.

Background Information：

Interleukin-7 (IL-7, 白血球介素-7) 是一種參與 B 細胞和 T 細胞發育的關鍵細胞激素。它在成熟 T 淋巴細胞的發育、存活、維持和恢復穩態中擔任重要角色，並且是 B 細胞發育過程中分化、存活、增殖和成熟的關鍵調節因子。此外，IL-7 可增強自然殺手 (NK) 細胞的抗病毒功能和擴增，並調節樹突狀細胞的發育和分化。據報導，IL-7 也參與中樞神經系統發育、肌肉生成和骨骼肌細胞遷移的調節（PMID：29663382；29655570；29449560）。
