Human AIM2 Baculovirus-Insect cells Overexpression Lysate: 产品信息
This Human AIM2 overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of AIM2 protein (Cat: 11654-H09B) from the overexpression lysate was verified.
A DNA sequence encoding the human AIM2 (NP_004824.1) (Met 1-Thr 343) was fused with the GST tag at the N-terminus.
The recombinant human AIM2/GST chimera consists of 567 amino acids and predicts a molecular mass of 65.2 kDa as estimated in SDS-PAGE under reducing conditions.
Human AIM2 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.

Human PYHIN4 Overexpression Lysate
AIM2, Absent In Melanoma 2 is a member of the interferon-inducible HIN-200 protein family that contains an amino-terminal pyrin domain and a carboxy-terminal oligonucleotide/oligosaccharide-binding domain, senses cytoplasmic DNA by means of its oligonucleotide/oligosaccharide-binding domain and interacts with ASC (apoptosis-associated speck-like protein containing a CARD) through its pyrin domain to activate caspase-1. In response to foreign cytoplasmic DNA, AIM2 forms an inflammasome, resulting in caspase activation in inflammatory cells. It had been pointed to a role of AIM2 function in both inflammation and cancer. AIM-2 antigen is expressed in a wide variety of tumor types, including neuroectodermal tumors, as well as breast, ovarian and colon carcinomas. AIM-2 could be used as a tumor antigen target for monitoring vaccine trials or to develop antigen specific active immunotherapy for glioma patients.
