背景資料

Bacteria are widely used for the expression of different proteins. However, 70-80% of the proteins expressed in bacteria by recombinant techniques are typically contained in insoluble inclusion bodies (i.e., protein aggregates). The protein of interest found in these sub-cellular structures is often inactive, due to incorrect folding. The production rate of recombinant proteins stored in inclusion bodies is invariably higher than those synthesized as soluble proteins. The reason behind this is thought to be the resistance of insoluble proteins to proteolysis by cellular enzymes. In addition, separation of insoluble recombinant proteins in inclusion bodies is considerably easier than that of soluble proteins. These factors have been the major influences favoring scale-up of high-value proteins using bacterial fermentation for example. Procedures for the purification of the expressed proteins from inclusion bodies are often labour-intensive, time consuming and not cost effective. This kit provides the essential reagents for cell disruption, inclusion body solubilization and purification using spin column chromatography - all optimized to work together thereby simplifying the process and saving a tremendous amount of time and cost.

產(chǎn)品描述

This kit provides everything required to isolate and purify inclusion body proteins from induced bacterial cultures. First a proprietary Cell Lysis Reagent is used to selectively lyse the cells and release inclusion bodies in their solid form. Next, inclusion bodies are dissolved and their contents released using the provided IB Solubilization Reagent. Inclusion body proteins are then further purified using spin columns for rapid and convenient buffer exchange and desalting. This kit provides a convenient way to screen recombinants prior to scaling up.

產(chǎn)品特點(diǎn)

The process is efficient and streamlined and can process up to 12 samples in only 60 minutes. Each spin column is able to recover up to 50 μg of acidic or basic proteins. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.

保存建議

Cell Lysis Reagent和IB Solubilization Reagent儲(chǔ)存在4°C。所有其他未開(kāi)封的溶液應(yīng)在室溫下儲(chǔ)存。一旦打開(kāi)，溶液應(yīng)儲(chǔ)存在4°C，除了堿性和酸性結(jié)合緩沖液，應(yīng)在室溫下儲(chǔ)存。具體保存情況收到產(chǎn)品后請(qǐng)按說(shuō)明書(shū)存放。
