Protein isolation is a technique that involves isolation and/ or purification of protein from cells or tissues via chromatography or electrophoresis. The major challenges in protein isolation include: 1. The concentration of proteins in cells is variable and tends to be small for some intracellular proteins. Unlike nucleic acids, proteins cannot be amplified. 2. Proteins are more unstable than nucleic acids. They are easily denatured under suboptimal temperature, pH or salt concentrations. 3. Finally, no generalized technique/protocol can be applied for protein isolation. Proteins may have different electrostatic (number of positively or negatively charged amino acids) or hydrophobic properties. Therefore, protein purification requires multiple steps depending on their charge (a negatively charged resin/column for positively charged proteins and vice-versa), dissolution (using detergents) and unlike in the case of DNA and RNA, instead of using salts, proteins should be isolated by isoelectric precipitation.

A key signature for necrotic cells is the permeabilization of the plasma membrane. Necrosis can be quantified by several cellular and biochemical assays. When studied minutely, it reveals the difficulty in confirmation in secondary induction of necrosis in apoptotic cells. Apoptotic cells are being analyzed to shift to necrotic status owing to membrane permeability at later stages, and thus, discrimination of two cell death becomes critical. Therefore, it is crucial to use a necrosis detection kit or a defined procedure to analyze this unprogrammed form of death in response to immense chemical and physical insults.
