Human Eotaxin-2 Baculovirus-Insect cells Overexpression Lysate: 产品信息
This Human Eotaxin-2 overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of Eotaxin-2 protein (Cat: 10901-H08B) from the overexpression lysate was verified.
A DNA sequence encoding the human CCL24 (O00175) (Met 1-Cys 119) was fused with a polyhistidine tag at the C-terminus.
The secreted recombinant human CCL24 consists of 103 amino acids and predicts a molecular mass of 11.8 kDa. It migrates as an approximately 19 KDa band in SDS-PAGE under reducing conditions.
Human Eotaxin-2 Baculovirus-Insect cells Overexpression Lysate: 使用指南
Cell lysate was prepared by homogenization of the over-expressed cells 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.
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.
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.

CCL24, also known as Eotaxin-2 and MPIF-2, belongs to the intercrine beta (chemokine CC) family. CCL24 gene belongs to the subfamily of small cytokine CC genes. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. CCL24 displays chemotactic activity on resting T lymphocytes, a minimal activity on neutrophils, and is negative on monocytes and activated T lymphocytes. CCL24 is also a strong suppressor of colony formation by a multipotential hematopoietic progenitor cell line. CCL24 is chemotactic for resting T-lymphocytes, and eosinophils. It has lower chemotactic activity for neutrophils but none for monocytes and activated lymphocytes. It is a strong suppressor of colony formation by a multipotential hematopoietic progenitor cell line. Eotaxin-2 interacts with chemokine receptor CCR3 to induce chemotaxis in eosinophils. Elevated level of Eotaxin-2 has been seen in patients with aspirin-exacerbated respiratory disease.
