Inmunocitoquímicas

Inmunocitoquímicas, also known as immunocytochemistry, is a laboratory technique used to detect specific antigens or proteins within cells using antibodies labeled with detectable markers. This method combines immunology and cytochemistry to enable the visualization of cellular components, aiding in the identification and characterization of various cell types and structures.

The process involves the application of a primary antibody that binds specifically to the target antigen. Subsequently, a secondary antibody conjugated to a detectable label, such as an enzyme (e.g., horseradish peroxidase) or a fluorescent dye, binds to the primary antibody. When a suitable substrate is applied, it produces a colorimetric or fluorescent signal indicating the presence and location of the target antigen within the cell.

Inmunocitoquímicas is widely used in medical and research settings for diagnostic purposes, including cancer identification, cell typing, and studying infectious agents. It provides valuable information about the cellular context of protein expression, aiding in understanding disease mechanisms and cellular functions.

This technique requires meticulous sample preparation, including fixation and sectioning, to preserve cellular architecture and antigenicity. Different detection systems and markers allow for a variety of applications, including multi-labeling for simultaneous detection of multiple antigens. Overall, inmunocitoquímicas is a vital tool in cytological and histological studies, offering specific and sensitive visualization of cellular components within complex tissues.
