人淋巴细胞趋化因子(Lymphotactin/XCL1) (Human)

产品描述:
Lymphotactin is the only known member of the C-chemokine family and signals through the receptor XCR1, formally known as GPR5. The spleen shows the highest level of lymphotactin compared to peripheral leukocytes, lung, colon and small intestine. Lymphotactin is chemotactic towards lymphocytes but not towards monocytes or neutrophils.
表达系统 :
Escherichia coli
溶解方法:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.
产品组成:
Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl.
存储条件:
This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
分子量:
Approximately 10.0 kDa, a single non-glycosylated polypeptide chain containing 92 amino acids.
内毒素:
Less than 1 EU/μg of Lymphotactin/XCL1 as determined by LAL method.
产品用途:
This material is offered by Cyagen Biosciences for research, laboratory or further evaluation purposes. FOR RESEARCH USE ONLY. NOT INTENDED FOR ANY ANIMAL OR HUMAN THERAP EUTIC OR DIAGNOSTIC USE.
生物学活性:
The biologically active determined by a chemotaxis bioassay using human T-lymphocytes is in a concentration of 10-100 ng/mL.
产品形态:
Sterile filtered white lyophilized (freeze-dried) powder.
