蛋白构建信息
A DNA sequence encoding the human CRIP2 (P52943) (Met1-Pro208) was expressed and purified.
分子量
The recombinant human CRIP2 consists of 210 amino acids and predicts a molecular mass of 22.6 KDa. It migrates as an approximately 26 KDa band in SDS-PAGE under reducing conditions.

Human CRIP2 Baculovirus-Insect cells Overexpression Lysate: 使用指南

制备方法
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.
裂解缓冲液
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.
使用建议
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.
缓冲液
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.
应用
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

CRIP2 背景信息

CRIP2 is a putative transcription factor. It has a widespread tissue expression and is highly expressed in heart. CRIP2 contains two LIM zinc-binding domains. CRIP2 may participate in the differentiation of smooth muscle tissue. It also plays an important role in esophageal squamous cell carcinoma (ESCC) tumorigenesis. CRIP2 acts as a transcription repressor of the NF-κB-mediated proangiogenic cytokine expression and thus functionally inhibits tumor formation and angiogenesis. It interacts with the NF-κB/p65 to inhibit its DNA-binding ability to the promoter regions of the major proangiogenesis cytokines critical for tumor progression, including IL6, IL8, and VEGF. In conclusion, we provide compelling evidence that CRIP2 acts as a transcription repressor of the NF-κB-mediated proangiogenic cytokine expression and thus functionally inhibits tumor formation and angiogenesis.
