Human Sorcin/SRI Baculovirus-Insect cells Overexpression Lysate: 产品信息
This Human Sorcin/SRI overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of Sorcin/SRI protein (Cat: 14547-HNCB) from the overexpression lysate was verified.
A DNA sequence encoding the human SRI (P30626) (Met1-Val198) was expressed and purified.
The recombinant human SRI consists of 200 amino acids and predicts a molecular mass of 21.8 KDa. It migrates as an approximately 20 KDa band in SDS-PAGE under reducing conditions.
Human Sorcin/SRI 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.

Sorcin was originally identified in multidrug-resistant cells. It is a calcium-binding protein. Sorcin modulates excitation-contraction coupling in the heart, contributes to calcium homeostasis in the heart sarcoplasmic reticulum. Sorcin is overexpressed in the multi-drug resistant chinese hamster ovary cell line CHRC5 and a variety of multidrug-resistant tumor cell lines, but overexpression is not a sufficient or necessary condition for the acquisition of the multidrug-resistant phenotype.
