Human Statherin HEK293 Overexpression Lysate: 产品信息
This Human Statherin overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Statherin protein (Cat: 13694-H05H) from the overexpression lysate was verified.
A DNA sequence encoding the human STATH (P02808-1) (Met1-Phe62) was fused with Fc region of mouse IgG at the C-terminus.
The recombinant human STATH/mFc is a disulfide-linked homodimer. The reduced monomer comprises 277 amino acids and has a predicted molecular mass of 31.6 kDa. The apparent molecular mass of the protein is approximately 36 in SDS-PAGE under reducing conditions.
Human Statherin HEK293 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 STATH Overexpression Lysate; Human STR Overexpression Lysate
Statherin, also known as STATH, belongs to the histatin/statherin family. Statherin may play an important role in the maintenance of oral health. It prevents calcium phospate precipitation in saliva, so maintaining a high calcium level in saliva and preventing teeth from dissolving. Statherin also inhibits spontaneous precipitation of calcium phosphate salts. Thus, statherin and PRPs may prevent build-up of harmful deposits in the salivary glands and on the tooth surfaces. Statherin is a highly stable salivary protein of low molecular mass (5,380).
