Thermo Scientific B-PER II Bacterial Protein Extraction Reagent (2X) is an easy-to-use cell lysis reagent is a nonionic detergent-based solutions that effectively disrupt cells and solubilize native or recombinant proteins without denaturation. All B-PER Reagents are compatible with downstream applications, such as affinity chromatography (e.g., immobilized metal affinity chromatography, glutathione chromatography), SDS-PAGE, and protein quantification (e.g., Pierce BCA Protein Assay, Pierce 660nm Protein Assay). Depending on the particular application, protease inhibitors, salts, reducing agents, denaturants, and chelating agents may be added to the reagent.

Features of the B-PER Bacterial Protein Extraction Reagent:

• 2X B-PER (detergent in Tris buffer; no enzyme components)
• Bacterial lysis
• Purification of proteins having low expression levels

All Thermo Scientific B-PER Protein Extraction Reagents are:
Ready to use—one-step cell lysis of gram-positive and gram-negative bacteria using a mild, nonionic detergent (proprietary) in Tris or phosphate buffer formulations
Fast and simple—just add B-PER Reagent to a bacterial pellet, incubate with mixing for 10 to 15 minutes and recover soluble proteins after pelleting the cell debris
Convenient B-PER Complete Reagent contains lysozyme and a universal nuclease in a single formulation with 4°C storage
Excellent yields—recover recombinant proteins from bacterial lysates or purify inclusion bodies to near-homogeneous levels
Flexible—B-PER Reagents are suitable for any scale of protein extraction and are available in phosphate and 1X and 2X Tris formulations, with and without enzymes
Compatible—completely compatible with addition of protease inhibitors, and the resulting protein extract can be used in protein assays, typical affinity purification methods (e.g., GST, 6xHis) and other applications

Convenient, Ready-to-use Formats
B-PER Bacterial Extraction Reagents are more effective than traditional sonication and typical homemade lysis buffers, many of which include detergents and components that interfere with downstream applications. B-PER Reagents are formulated in Tris or phosphate buffer at physiological pH. They extract native and soluble recombinant proteins and yield lysates that are directly compatible with most downstream workflows such as electrophoresis, affinity purification, immunoprecipitation, protein interaction analysis, crosslinking and protein labeling.

常见问题解答 (FAQ)

细菌无法用B-PER试剂裂解,这是什么原因所致?

在富营养培养基(高糖)中生长的细菌往往难以裂解。您可以尝试减少葡萄糖浓度。B-PER试剂能够裂解包括E. coli,Acetinobacter,Archaebacteria,S. aureus,H. pylori,昆虫杆状病毒,线虫和昆虫细胞在内的细菌和细胞。B-PER试剂可以裂解一些革兰氏阳性菌,但是裂解革兰氏阴性细菌的效率通常更高。如果对某一特定细菌菌株裂解效果不佳,则请在裂解前冷冻细菌。添加溶菌酶是最有效的提取手段,但是对于一些过表达蛋白则不需要加入溶菌酶。

What is the difference between B-PER and B-PER II Reagent?

B-PER II Reagent contains more detergent making it ideal for extracting proteins from small bacterial cultures with less than 20 mL in volume.

What is the composition of B-PER Reagent?

B-PER Reagent utilizes a proprietary, mild nonionic detergent in a 20 mM Tris HCl, pH 7.5 buffer. No enzymatic components are present in the B-PER solution itself (B-PER Complete Bacterial Protein Extraction Reagent, Cat. No. 89821, 89822 does contain enzymes). Depending on your particular protein, you may need to add components such as salt, lysozyme, protease inhibitors, reducing agents and chelating agents. Other ready-to-use formats include B-PER II Bacterial Protein Extraction Reagent (2X), B-PER Reagent (in Phosphate Buffer), and B-PER with Enzymes Bacterial Protein Extraction Kit.

What is the volume of B-PER Extraction Reagent to use per gram weight of wet cells?

For 1 gram of cells add 4 mL of B-PER Reagent.

Will my protein be in its native conformation after B-PER Reagent extraction?

While this is protein-dependent, many proteins have been successfully tested in downstream applications (reporter assays, immunoprecipitation and beta-Gal assays), including GST and 6xHis proteins. Otherwise, samples can be diluted or dialyzed to remove any interfering substances.
