BONCAT (Bioorthogonal Non-canonical Amino Acid Tagging): a method to define t...
Tuesday, May 15, 2018

Living entities have a tightly regulated dynamic system, where majority of the energy expenditure goes for maintaining the homeostasis. Most of the biological processes such as growth, development, metabolism etc are regulated at the crucial control point of protein translation and degradation (r... ..

Basics of Using Cytology for Cancer Testing
Tuesday, May 1, 2018

Aside from tissue biopsy, cytology serves as an indispensable tool in screening and diagnosing cancer. In this technique, a cytological material is obtained from the patient, spread onto glass slides for microscopic examination, stained, screened for abnormalities and assessed prior to the issuan... ..

Friday, April 13, 2018

This is a follow up blog to SILAC for Improved Mass Spectrometry & Quantitative Proteomics SILAC (Stable Isotope Labeling with Amino Acids in Cell Culture) method of working is differentiated into two critical phases: an adaptation phase and an experimental phase. Before initiating the adapta... ..

SILAC for Improved Mass Spectrometry & Quantitative Proteomics
Friday, April 13, 2018

SILAC (Stable Isotope Labeling with Amino Acids in Cell Culture) Quantitative proteomics has been a cutting-edge and demanding field in biological research for the past few decades. With the advancement of technology, MS (Mass spectrometry) based methods have become strikingly helpful tools, whic... ..

Key Differences of H&E and Special Stains for Immunohistochemistry
Wednesday, March 28, 2018

Routine H&E (Haemotoxylin and Eosin stains) and special staining comes especially handy when examining tissue structure and cell types and/or when looking for the presence of certain microorganisms in a sample. While both stains are used in histopathology laboratories, H&E stain is more c... ..

Study Protein to Protein Interaction with Protein Cross Linking to Glass
Friday, March 23, 2018

In all the complex biological processes, the mechanism underlies a synchronized and orchestrated molecular organization, which works through protein-protein interactions. These interactions could be transient, such as catalytic or signal-transduction pathways, requiring a transitory protein-... ..

When to Use Immunohistochemistry (IHC) Detection vs. a Direct Method
Tuesday, March 6, 2018

How do you know which method to use for visualizing proteins after immunodetection? Should you be using the direct detection method or would applying an indirect detection method best serve your purpose? If you’re not sure which method to use, here are some things you definitely need to know. ..

Traction Force Microscopy for cell interaction with extracellular matrix
Tuesday, February 27, 2018

The fundamental source of all processes in living system is force. Force is required to maintain the balance between the external and internal environment of any living system. Cells have the ability to sense and respond to the forces. Cells perform different activities such as migration and inte... ..

Immunoprecipitation Protocol: Critical Parameters
Tuesday, February 13, 2018

Following up the Immunoprecipitation Protocol: The Basics , we explore the IP protocol from the viewpoint of some of the protocols critical parameters. Antigen extraction: As mentioned in the general protocol , cellular antigens are required to be extracted from a suitable source depending on the... ..

Immunoprecipitation Protocol: The Basics
Tuesday, February 6, 2018

The cardinal principle behind immunoprecipitation (IP) is the isolation of an antigen by interaction between the antigen and a specific antibody conjugated to a sedimentable matrix. Antigen source may vary from cells or tissues without labeling, radio labeled or tagged cells, labeled&nb... ..
