Manufacturing AAVs or lentiviral Vectors

 Let's suppose you have one or more great gene candidates. Now you have completed all in vitro studies. You need to validate the results in vivo. You will find thousands data of amazing results Adenoviral Associated Vectors. You may have the question "What serotype do you need for my project?”. The bibliography will give you a clear answer.

There is a good chance to select the right serotype for your cells. Different labs may use different types depending on the targeting issue. However, they can also use different types based on the cell. On the other hand, lentiviral vectors, or LVs, are VSV-G pseudo typed, it allows them to transduce any cell from any species.

AAVs cannot integrate the target cells' genomes are remain within the cells. LVs, on the other hand, are integrative and can provide stable expression. AAVs are smaller than LVs and have a greater spread rate within specific tissues. This advantage comes with a drawback. Lentiviral vectors can contain a 10kb insert, while an expression cassette can only hold 4,5 kb.

You can use Both LVs and AAVs to transfer genes. They can induce gene expression in quiescent and dividing cells. And usually don't trigger an immune response. To avoid an inflammatory response (3), and to maintain the original cell phenotypes. It is important to ensure the purity of any vector used is maintained.

The lentiviral vector, is your best friend.  If you want to target a specific cell population without affecting others in the same tissue. A specific promoter is a smart choice. You can use Lentiviruses Manufacturing to validate your strategy in vitro. AAVs can't modify cell cultures and adding a promoter. If you want to your construct could result in a cassette, it is too large for an AAV (limit of 4.5kb). Click here for more information about promoters.

If you are looking for a system that is as efficient as the LVs. But with no integrative properties, then you could also consider no integrative. You can use no integrative articles such as LentiFlash(TM), RNAs delivered directly to the cells. This is a smart choice for transient modifications of cells or genome editing in-vivo.

Are you still unsure which delivery tool to use? This flow chart will help you choose the best delivery tool for your experiments.

What is CAR T-cell therapy? And how it Works?

CAR T-cell therapy is a type of cancer therapy that uses a patient’s own modified white blood cells to kill cancer cells. 

How does CAR T-cell therapy work? 

The procedure begins by collecting blood from the patient with cancer. throughout this process, T cells are alienated and removed from the blood and the remaining blood is returned to the body. 

Chimeric Antigen Receptor or CAR technology and its application on tumor therapy are as below: 

• CAR T in Vitro Assay 
• CAR expression validation 
• CAR-T cell proliferation 

How Long Does The Patient Remain In The Hospital Following CAR T-Cell Therapy? 

Patients typically need to stay in the hospital one to one and one-half weeks after receiving CAR T-cell therapy. measurement lengthwise of stay depends on many factors counting the patient’s response to treatment and the danger for side effects. 

What’s the victory rate of CAR T-cell therapy for lymphoma? 

Over 80 percent of patients who received in clinical trials experienced either a complete or partial response. (A complete response means there were no signs of cancer; partial response means there was some reduction in the extent of cancer.)

Anti-idiotypic Antibody in Antibody Drug Development

An anti-idiotype/anti-idiotypic antibody (Anti-ID Ab) binds to the idiotype of another antibody, usually an antibody drug. An idiotype can be defined as the specific combination of idiotopes present within an antibody's complement determining regions. Since anti-idiotype/anti-idiotypic Abs are capable of binding to antibody drugs within biological fluids, they are commonly used in preclinical setting for antibody drug pharmacokinetics (PK) and pharmacodynamics (PD). Due to the similarity between anti-idiotype/anti-idiotypic Abs and anti-drug antibodies, anti-idiotype/anti-idiotypic Abs are also commonly used as reference standard for antibody drug immunogenicity, anti-drug antibody (ADA) studies.

There are 3 types of anti-idiotype/anti-idiotypic Abs: Antigen-blocking & Non-blocking and Complex-specific antibody. Due to the fact that Complex-specific antibody is usually difficult to develop, the first two types (Antigen-blocking & Non-blocking) are usually applied, and the content of bound drug can be obtained by calculation.

Specifically binding to the idiotype of antibody drug, Anti-ID Ab is an indispensable tool in pharmacokinetic study for detecting and quantitating Ab drug in human and animal serum. Due to the good homogeneity and specificity of anti-ID monoclonal antibody, It is recommended for usage in the preclinical stage, pharmaceutical research and clinical stage.

And for Anti-ID polyclonal antibody or antigen capture ELISA could be used in drug discovery stage. In terms of detection sensitivity, mouse Anti-ID mAb can be developed for ng-level detection. If the sensitivity is expected to reach the pg level, the development of rabbit anti-ID mAb is also the option. Due to the similarity between anti-ID and anti-drug antibody, it can also be used as a positive control of anti-drug antibody in immunogenicity study for the determination of total anti-drug antibody. Specifically, anti-ID polyclonal antibodies is recommended as the positive control of anti-drug antibody due to its high coverage property, which could simulate anti-drug antibody to the greatest extent. For the detection of neutralizing anti-drug antibody, anti-ID mAb which could block the binding of drug to target shall be developed as control. Pharmacokinetic and immunogenicity analysis cover the whole process of biologics development. As an essential tool antibody, anti-ID is not only one of the critical reagents for IND filing, but also widely used in the clinical stage.

What Are Cell Therapy Plasmid And What Is Their Importance?

Plasmids are widely used vectors in gene and cell therapy products. When producing a cell or gene therapy product, plasmid can be used as raw materials to produce viral vectors. Cell therapy plasmid and gene therapy plasmid usually carry the Gene of Interest, and using helper plasmids and transfer plasmid, viral vector will be packaged, which will finally transduce effector cells in cell therapy, and will be injected directly into patient body in gene therapy.

Cell therapy plasmid and gene therapy plasmid are important in delivering Gene of Interest and packaging viral vectors. Therefore, the helper plasmids and backbone of transfer plasmid are crucial, in order to improve the transfection rate. In addition, as a raw material for the production of cell and gene therapy products, the quality of plasmids should be well controlled. The purity of the cell therapy and gene therapy plasmid, for example, the supercoiled plasmid content, has direct influence on the transfection rate. And the impurities can also influence the safety and efficacy of the final product.

Plasmid in cell therapy and gene therapy is an important material, which can affect the quality, safety and efficacy of the final product. Therefore, more attention should be paid to the manufacturing of cell therapy plasmid and gene therapy plasmid.
