Transfection is a powerful technique that enables the study of the function of genes and gene products in cells. Based on the nature of experiments, we may need a stable DNA transfection in cells for persistent gain-of-function or loss-of-function of the target gene. For stable transfection, integration of a DNA vector into the chromosome is crucial which requires selective screening and clonal isolation. By carefully selecting a viral delivery system and related reagents we can ensure safe and highly-efficient delivery of expression constructs for high-level constitutive or inducible expression in any mammalian cell type.

Protein ladders are a set of standards known as molecular weight proteins that are utilized to identify the approximate size of a protein molecule run on a PAGE gel electrophoresis. The challenges in running the ladders are the choice of appropriate protein standard as it is used as visual evidence of protein migration, transfer efficiency, and positive control. Suitable protein markers can be selected on the basis of required properties and applications, i.e., fluorescent ladder, IEF, 2D SDS-PAGE ladder, natural ladder with an isoelectric point, and optimized ladders for Western Blot chemiluminescence detection. The key factors for running a distinct protein ladder are buffer conditions, charge/voltage at migration time, and the gel's concentration.

Cell Invasion or Cell Migration assays are technically challenging to set up as the gradient between the two compartments equilibrates in time during the assay. It is also problematic to view cells and for cells to migrate through a non-physiologic polycarbonate or polypropylene filter. Care must be taken while loading the well with cells to form a single cell suspension. Precaution must be taken while trypsinization (under-trypsinization can lead to cell clumping while over-trypsinization could strip off adhesion molecules necessary for migration). This leads to difficulty in getting significant results, when only small numbers of cells cross the filter or when the distribution and/or staining of the cells is uneven
