Human CCL26/Eotaxin-3 Baculovirus-Insect Overexpression Lysate


Human CCL26/Eotaxin-3 Baculovirus-Insect Overexpression Lysate: 产品信息

This Human CCL26/Eotaxin-3 overexpression lysate was created in Baculovirus-Insect Cells and intented for use as a Western blot (WB) positive control. Purification of CCL26/Eotaxin-3 protein (Cat: 10577-HNAB) from the overexpression lysate was verified.
Baculovirus-Insect Cells
A DNA sequence encoding the human CCL26 (NP_006063.1) (Met1-Leu94) was expressed.
The recombinant human CCL26 consists of 71 amino acids and predicts a molecular mass of 8.4 kDa.

Human CCL26/Eotaxin-3 Baculovirus-Insect Overexpression Lysate: 使用指南

Cell lysate was prepared by homogenization in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min. 3. Store the lyophilized cell lysate at 4℃. After re-dissolution, recommend to aliquot it into smaller quantities and store at -80℃.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

CCL26/Eotaxin-3 背景信息

The eotaxin subfamily of CC chemokines consists of eotaxin-1/CCL11, eotaxin-2/CCL24 and eotaxin-3/CCL26. All eotaxins induce the trafficking of eosinophils to the sites of inflammation via CC chemokine receptor 3 (CCR3), which is also expressed by several different cell types, including basophils, dendritic cells, smooth muscle cells, epithelial cells and fibroblasts. The sequence similarity between the three eotaxins is limited (<4%), but their functional properties are very similar. Eotaxin-1 and -2 are expressed by both haematopoietic and non-haematopoietic cells, but eotaxin-3 expression has been reported to be limited to non-haematopoietic cells. Interleukin (IL)-4 is the main inducer for eotaxin-3 expression, whereas eotaxin-1 is up-regulated by IL-4 and the proinflammatory cytokine tumour necrosis factor (TNF)-α. Eotaxin-3 is expressed in vascular endothelial cells and human dermal fibroblasts after IL-4 and IL-13 stimulation, and this is dependent upon the IL-4-/IL-13-specific transcription factor, signal transducers and activator of transcription (STAT)-6. Eotaxin-3 is expressed on the surface of IL-4-stimulated endothelial cells and promotes eosinophil transmigration.
