HPLC columns, SeQuant® ZIC®-pHILIC
Supplier: Merck
ZIC®-pHILIC has the same stationary phase as ZIC®-HILIC, but is instead based on a polymeric particle for enhanced pH stability. The lack of silica practically nullifies background in high sensitivity detectors such as charged aerosol used for determination of organic and inorganic ions.

HPLC columns, SeQuant® ZIC®-cHILIC
Supplier: Merck
ZIC®-cHILIC is based on the same technology platform as ZIC®-HILIC, but has a different functional group and an improved manufacturing procedure. The different charge orientation of the zwitterionic functional group leads to a different – and complementary – selectivity for polar hydrophilic compounds. This selectivity is especially beneficial for hydrophilic compounds that are negatively charged, positively charged, zwitterionic or neutral, for example, organic acids, amino acids, metabolites, aminoglycosides and nucleotides.

HPLC columns, SeQuant® ZIC®-HILIC
Supplier: Merck
The selectivity offered by ZIC®-HILIC is suitable for a wide variety of molecules containing hydrophilic or ionisable functional groups. This includes compounds such as carbohydrates, metabolites, acids and bases, organic and inorganic ions, metal complexes, amino acids, peptides, protein digests, plant and cell extracts, plus much more. Such compounds are normally characterised by a small or negative LogP value and have poor retention on reversed-phase columns.

Protein extraction reagents, BugBuster® and BugBuster® plus Benzonase®, Millipore®
Supplier: Merck Millipore (Novagen)
BugBuster® Protein Extraction reagent is formulated for the gentle disruption of the cell wall of E. coli, liberating soluble protein. It provides a simple, rapid, low-cost alternative to mechanical methods such as French Press or sonication for releasing expressed target protein in preparation for purification or other applications. The formulation utilises a detergent mix that is capable of cell wall perforation without denaturing soluble protein.

Protein extraction reagent, BugBuster® HT, Millipore®
Supplier: Merck Millipore (Novagen)
BugBuster® HT Protein Extraction Reagent combines BugBuster® Protein Extraction Reagent and Benzonase® Nuclease in one convenient reagent. BugBuster® HT eliminates common bioprocessing problems resulting from traditional cell lysis procedures. Soluble proteins are gently extracted from E. coli without exposure to heat or oxidative damage and viscosity is eliminated by nucleic acid digestion in a single step. The resulting protein extract can easily be fractionated by conventional purification techniques. BugBuster HT is ideally suited for application in high throughput protein purifications.

Protein extraction reagent, BugBuster® 10X, Millipore®
Supplier: Merck Millipore (Novagen)
BugBuster® 10X is a concentrated formulation of the proprietary detergents employed in BugBuster® without the addition of salts or buffer components. Concentrated BugBuster® provides a flexible alternative to the ready-to-use standard 1X BugBuster®, allowing user-defined dilution and addition of buffer components. BugBuster® 10X has all of the bioprocessing benefits of standard BugBuster® plus the freedom to control pH, reagent concentration, and buffer additives necessary for maximum extraction and activity of your target protein.

Protein extraction reagent, BugBuster® (primary amine-free), Millipore®
Supplier: Merck Millipore (Novagen)
BugBuster® (primary amine-free) Protein Extraction Reagent is a special formulation of BugBuster designed for applications where primary amines would interfere if present in the protein extract, such as protein immobilisation or cross-linking. The PIPPS buffer used in BugBuster® (primary amine-free) has a similar buffer capacity and pH range as the original Tris-buffered BugBuster®, but will not complex metal ions, also making it ideally suited for extraction of metal dependent proteins.
