IL-20细胞因子,重组小鼠白介素20,重组蛋白,E.col

重组小鼠白介素20蛋白 (IL-20)，无动物源表达，带His标签

货号：PRP1109 | 产品类型：细胞因子 | 种属：小鼠

产品概述

本产品为重组小鼠IL-20细胞因子蛋白，采用无动物源的大肠杆菌表达系统生产，C末端带有His标签，具备高纯度与可靠的生物活性，适用于细胞培养及相关体外功能研究。

关键特性

• 高纯度：经SDS-PAGE检测，纯度 > 98%
• 低内毒素：LAL法检测，内毒素含量 < 0.1 EU/μg
• 无动物源表达：生产过程无动物组分，降低外源因子风险
• 冻干形态：以无菌PBS（pH 7.4）为缓冲液，便于储存与运输

生物活性

通过BaF3细胞（转染人IL-20 Rα与IL-20 Rβ）增殖实验测定，其ED₅₀值 < 2 ng/mL，表明该蛋白具有优异的受体结合与功能诱导能力。

蛋白结构与表达信息

• 序列来源：小鼠源IL-20 (Leu25-Leu176) (UniProt: Q9JKV9)
• 蛋白长度：152个氨基酸
• 预测分子量：18.52 kDa
• 实际观测分子量：约18.52 kDa（还原性SDS-PAGE）
• 表达系统：大肠杆菌（E.coli）

使用建议

• 复溶方法：推荐使用配套复溶缓冲液，浓度建议不低于100 µg/mL
• 保存条件：冻干粉-20°C可保存1年；复溶后于2-8°C可稳定保存1周
• 长期保存：建议在含载体蛋白（如0.1% BSA）的缓冲液中分装后，于-20°C或-80°C保存，避免反复冻融

背景信息

白细胞介素20（IL-20）属于IL-20细胞因子亚家族，该家族包括IL-19、IL-20、IL-22、IL-24和IL-26。其在炎症过程中调节角质形成细胞分化，并对多能造血祖细胞的扩增具有重要作用。

Recombinant Mouse Interleukin-20 Protein (IL‑20), Animal‑Component‑Free Expression, His‑Tag

Product No.：PRP1109 | Product Type：Cytokine | Species：Mouse

Product Overview

This product is a recombinant mouse IL‑20 cytokine protein produced using an animal‑component‑free Escherichia coli expression system. It carries a C‑terminal His tag, exhibits high purity and reliable bioactivity, and is suitable for cell culture and related in‑vitro functional studies.

Key Features

• High Purity：SDS‑PAGE analysis shows purity > 98%
• Low Endotoxin：LAL assay detects endotoxin < 0.1 EU/µg
• Animal‑Component‑Free Expression：production process contains no animal‑derived components, reducing risk of exogenous factors
• Lyophilized Form：supplied in sterile PBS (pH 7.4) as buffer, facilitating storage and transport

Biological Activity

Determined by a proliferation assay using BaF3 cells transfected with human IL‑20Rα and IL‑20Rβ, the ED₅₀ is < 2 ng/mL, indicating excellent receptor binding and functional induction capability.

Protein Structure and Expression Information

• Sequence Source：mouse IL‑20 (Leu25‑Leu176) (UniProt: Q9JKV9)
• Protein Length：152 amino acids
• Predicted Molecular Weight：18.52 kDa
• Observed Molecular Weight：~18.52 kDa (reducing SDS‑PAGE)
• Expression System：Escherichia coli (E.coli)

Recommended Use

• Reconstitution：recommended to use the supplied reconstitution buffer; final concentration should not be lower than 100 µg/mL
• Storage Conditions：lyophilized powder stable at –20 °C for 1 year; after reconstitution, stable at 2‑8 °C for 1 week
• Long‑Term Storage：aliquot into buffer containing a carrier protein (e.g., 0.1 % BSA) and store at –20 °C or –80 °C; avoid repeated freeze‑thaw cycles

Background

Interleukin‑20 (IL‑20) belongs to the IL‑20 cytokine subfamily, which includes IL‑19, IL‑20, IL‑22, IL‑24, and IL‑26. It regulates keratinocyte differentiation during inflammation and plays a critical role in the expansion of multipotent hematopoietic progenitor cells.
