buffers

Resistendo alle variazioni di pH, i tamponi proteggono i campioni quando vengono aggiunti acidi o basi. Disponibili in polvere e in forma liquida, tracciano efficacemente le proteine durante l'isolamento e la separazione tramite elettroforesi. I tamponi salati possono anche essere utilizzati per calibrare e standardizzare i pHmetri per ottenere letture accurate. Le sostanze bloccanti impediscono l'adesione degli anticorpi ai siti liberi dalla membrana, che produrrebbero un background interferente. In varie concentrazioni per soddisfare qualsiasi esigenza, i tamponi possono essere disponibili in formato liquido o disidratato.

Nuclear and cytoplasmic extraction reagents, NE-PER

Supplier: Thermo Fisher Scientific

The NE-PER Nuclear and Cytoplasmic Extraction Kit provides for efficient cell lysis and extraction of separate cytoplasmic and nuclear protein fractions in less than two hours. The nuclear protein extraction method involves simple, stepwise lysis of cells and centrifugal isolation of nuclear and cytoplasmic protein fractions. A benchtop microcentrifuge, tubes and pipettors are the only tools required. The NE-PER Reagents efficiently solubilise and separate cytoplasmic and nuclear proteins into fractions with minimal cross-contamination or interference from genomic DNA and mRNA. The isolated proteins can be used to perform immunoassays as well as protein interaction studies such as mobility shift assays (EMSA), co-immunoprecipitation (Co-IP) and pull-down assays.

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.

Reagenti per estrazione proteica, BugBuster® e BugBuster® plus Benzonase®, Millipore®

Supplier: Merck Millipore (Novagen)

Il reagente per estrazione proteica BugBuster® è formulato espressamente per una lisi delicata della parete cellulare dell'E. coli e per la conseguente liberazione delle proteine solubili. Questo reagente rappresenta un'alternativa semplice, rapida ed economica ai metodi meccanici (frammentazione a pressione 'French Press' o sonicazione) per il rilascio delle proteine bersaglio prima della purificazione o di altre applicazioni. Nella sua formulazione, il reagente utilizza una miscela di detergenti in grado di perforare la parete cellulare senza denaturare le proteine solubili.
