IL-5 Protein, Canine, Recombin

蛋白长度：A DNA sequence encoding the extracellular domain of canine IL5 (NP_001006951.1) (Met 1-Ser 134) was expressed, with a polyhistidine tag at the C-terminus.

性质：

表达系统：Baculovirus-Insect Cells

种属：Canine

氨基酸序：Met1-Ser134

标签类型：C-His

分子量：The recombinant canine IL5 consists of 123 amino acids and has a predicted molecular mass of 14.5 kDa. As a result of glycosylation, the apparent molecular mass of the canine IL5 is approximately 17-19 kDa in SDS-PAGE under reducing conditions.

活性：Measured in a cell proliferation assay using TF-1 human erythroleukemic cells.The EDfor this effect is typically 2-8 ng/mL.

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method.

基因名称：interleukin 5

通用名：IL5

蛋白序参考：NP_001006951.1

总结：Interleukin 5 (IL-5) is a member of the interleukin family with a length of 115 amino acids. Interleukins are a group of cytokines (secreted proteins/signaling molecules) that were first seen to be expressed by white blood cells (leukocytes) and has been found in a wide variety of body cells. Interleukin 5 or IL-5 is produced by T helper-2 cells and mast cells. It helps to stimulate B cell growth and increase immunoglobulin secretion and is considered a key mediator in eosinophil activation. Interleukin 5 (IL-5) has long been associated with several allergic diseases, including allergic rhinitis and asthma. Growth in the number of circulating, airway tissue, and induced sputum eosinophils have been observed in patients with these diseases. IL-5 also had something with the terminally differentiated granulocyte eosinophils. IL-5 was originally found as an eosinophil colony-stimulating factor. It has been proved to be a major regulator of eosinophil accumulation in tissues and can modulate eosinophil behavior at every stage from maturation to survival.

形式：Lyophilized

纯度：> 98 % as determined by SDS-PAGE.

储存条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.

储存溶液：Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 8.5, 10% gly Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
