Agilent Technologies this week launched the High Sensitivity Protein 250 Kit for the company’s 2100 bioanalyzer. The kit is designed for pharmaceutical QA/QC and life science research applications and detects proteins down to as little as 1 picogram per microliter, which Agilent said is comparable to or better than silver-staining slab gels.
The kit features a dynamic range of four orders of magnitude for quantification and covers a sizing range of 10 to 250 kiloDaltons. Separation, quantitation, and purity measurements can be done in a single step, and typical throughput for QA/QC is 10 samples per hour, Agilent said in a statement. Each kit analyzes up to 100 samples.
Phenomenex introduced the 3 micrometer C18 300 Å HPLC column this week. The C18 reverse phase column is the most efficient of the company’s Jupiter line of products of protein characterization and purification, Phenomenex said in a statement, and provides better resolution and sharper peaks than other phases “enabling the separation of closely eluting proteins.”
