Retlirafusp Biosimilar – Anti-CD274 mAb – Research Grade

Description of Retlirafusp Biosimilar - Anti-CD274 mAb - Research Grade

Introduction

Retlirafusp Biosimilar, also known as Anti-CD274 mAb, is a research grade antibody that has shown promising results in the field of cancer therapy. This biosimilar is a monoclonal antibody that specifically targets the CD274 protein, also known as programmed cell death ligand 1 (PD-L1). In this article, we will delve into the structure, activity, and potential applications of Retlirafusp Biosimilar.

Structure of Retlirafusp Biosimilar

Retlirafusp Biosimilar is a recombinant humanized monoclonal antibody that is produced using advanced genetic engineering techniques. It is composed of two identical heavy chains and two identical light chains, each consisting of approximately 450 amino acids. The antibody has a molecular weight of approximately 150 kDa.

The variable region of Retlirafusp Biosimilar is responsible for its specificity towards CD274 protein. This region is located at the tip of the antibody and is composed of six complementarity-determining regions (CDRs). These CDRs interact with specific amino acid sequences on the CD274 protein, allowing the antibody to bind to it with high affinity.

Activity of Retlirafusp Biosimilar

Retlirafusp Biosimilar exerts its activity by binding to the CD274 protein on the surface of cancer cells. CD274 protein is known to be overexpressed in various types of cancer, including lung, breast, and bladder cancer. This overexpression of CD274 protein allows cancer cells to evade the immune system and continue to grow and spread.

By binding to CD274 protein, Retlirafusp Biosimilar blocks its interaction with the programmed cell death protein 1 (PD-1) on immune cells. This interaction between CD274 and PD-1 is known to inhibit the activity of immune cells, allowing cancer cells to escape detection and destruction. By blocking this interaction, Retlirafusp Biosimilar enhances the activity of immune cells and promotes the destruction of cancer cells.

Potential Applications of Retlirafusp Biosimilar

Retlirafusp Biosimilar has shown promising results in preclinical studies and is currently being evaluated in clinical trials for the treatment of various types of cancer. Some potential applications of this biosimilar include:
