XCL2/SCM-1 beta 蛋白, Human (sf9, His)

目录号: HY-P74461
COA 产品使用指南

XCL2 (也称为 SCM1-β 和 SCYC-2) 是与 XCL1 高度相关的 C 趋化因子亚家族的成员。XCL2 结合并激活 G 蛋白偶联受体 XCR1。XCL2 主要由活化的 T 细胞和自然杀伤细胞产生。XCL2/SCM-1 beta 蛋白, Human (sf9, His) 由 sf9 昆虫细胞表达产生,由 114 个氨基酸 (M1-G114) 组成,其 C 末端带有 His 标签。

描述

XCL2 (also knowns as SCM1-β and SCYC-2) is a member of C chemokine sub-family that is highly related to XCL1. XCL2 binds and activates the G protein-coupled receptor, XCR1. XCL2 is mainly produced by activated T cells and natural killer cells[1]. XCL2/SCM-1 beta Protein, Human (sf9, His) is produced in sf9 insect cells with a C-Terminal His-tag. It consists of 114 amino acids (M1-G114).

研究背景

XCL1XCL2 氨基酸序列的比对说明了它们的高度相似性。人类蛋白质仅在两个序列位置上有所不同,分别是 XCL1XCL2 中的 7DK8 和 7HR8。XCL2 由未刺激的自然杀伤 (NK) 细胞组成型表达,并且在较小程度上由非活性 CD8 + T 细胞[1]表达。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
