基因名
XCL2/SCM-1 beta
-
简介
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).

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.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Protein Description
XCL2, also known as SCM-1 beta, is a small cytokine belonging to the C chemokine family. It plays a crucial role in modulating immune responses, particularly in the attraction of lymphocytes to sites of inflammation and infection. The research surrounding XCL2/SCM-1 beta has gained momentum due to its implications in various autoimmune diseases, cancer, and viral infections. Elevated levels of this chemokine have been associated with disease progression, highlighting its potential as a biomarker for diagnostic and therapeutic purposes. Furthermore, XCL2's ability to selectively recruit lymphocytes, especially theC-C chemokine receptor type 4 (CCR4)-expressing T cells, positions it as a target for immunotherapeutic strategies. The production of recombinant XCL2/SCM-1 beta protein has become increasingly important for studying its biological functions, signaling pathways, and potential interactions with other immune modulators. This research not only elucidates the fundamental mechanisms of immune regulation but also opens avenues for the development of novel therapeutic interventions aimed at modulating the immune response in various pathological conditions.
