Multiplex Protein Assays: which one fits you best?

06/09/2019 by Isabelle Nobiron, PhD No Comments

Multiplex protein assays allow multiple targets quantification in a single sample, a bit like performing up to 40 different ELISAs in one go. Outsourcing Multiplex Protein Quantification projects to experts may work out more cost effective and time saving. It saves you the hassle of setting up a new technology in your lab, and you can rely on people with years of expertise in the technology to generate quality data on the very first run. Should you wish to set it up in your own lab, some technologies are easily adaptable if you have access to the equipment.

Renal injury biomarkers

25/07/2016 by Philippe Fixe, PhD No Comments
Kidney, Renin, Angiotensin

Renal injury can sometimes be induced by drugs. Some examples of renal damage-inducing drugs include some widespread treatments, such as ß-Lactam antibiotics, bisphosphonates, non-steroidal anti-inflammatory drugs, diuretics, aminoglycoside antibiotics, antineoplastic agents and radiocontrast agents.

Since 2008, both the FDA and the EMEA indicated that additional tests may be necessary to assess new drug safety and prevent from renal toxicity. Though these recommendations are voluntary, many pharmaceutical companies have started gathering data on nephrotoxicity biomarkers.

Global cytokine profiles and cancer drug resistance

10/05/2016 by Philippe Fixe, PhD No Comments
BBA Reviews on Cancer

The role of the interactions between tumor cells and their microenvironment (TME) is now well-established in various stages of cancer development. Cytokines, produced by both the cancer and the immune cells, actively contribute to these critical connections (see the previous posts related to the crosstalk between cancer and immune cells in relation to tumor escape, immunoediting and immunosurveillance).

BBA Reviews on CancerIn a recent review published in BBA, RayBiotech‘s team highlights the “cytokine signatures and dynamics” seen during cancer development. They also demonstrate the necessity of designing relevant multiplex immunoassays for the profiling and the quantification of cytokines in biomarker and anti-cancer drug discovery programs.

How sample preparation can affect your biomarker studies (II)

11/12/2015 by Ana Arraztio No Comments

In a previous post, we looked at the importance of sample preparation methods depending on the biomarker being studied (e.g. MMPs, cytokines). Today, let’s focus on cell / tissue lysates.
