Price Update,Human CMV pp65 (495-503) peptide

The development of robust research tools is paramount in understanding complex biological processes, particularly in the realm of immunology. When investigating the human immune system's response to cytomegalovirus (CMV), specific peptides play a crucial role. This article delves into the availability and applications of CMV peptides for sale, providing researchers with verifiable information and detailed insights into these vital research components.

Understanding CMV and its Immunological Significance

Cytomegalovirus (CMV), also known as Human herpesvirus 5, is a common virus that infects most people at some point in their lives. While often asymptomatic in healthy individuals, CMV can cause serious health problems in those with weakened immune systems, such as transplant recipients or individuals with HIV/AIDS. A key target of the immune response to CMV is the 65 kDa phosphoprotein, pp65. This protein is a significant immunodominant antigen, meaning it elicits a strong immune response, particularly from T-cells. Research into these responses often utilizes specific peptide fragments of pp65 to stimulate and analyze immune cells.

The Role of CMV Peptides in Research

CMV peptides are short chains of amino acids that represent specific regions of CMV proteins, most notably the CMV pp65 antigen. These peptides are instrumental in a variety of immunological assays. They are frequently used to:

* Stimulate T-cell responses: Researchers can use CMV peptides to activate specific T-cell populations (both CD4+ and CD8+) in vitro. This allows for the study of T-cell functionality, cytokine production, and cytotoxic T-lymphocyte (CTL) activity.

* Assess immune status: In clinical research, CMV peptide stimulation assays can help determine an individual's immune status against CMV, identifying those with cellular immunity.

* Develop diagnostic tools: Understanding which CMV epitopes are recognized by the immune system can aid in the development of more precise diagnostic and prognostic tools.

* Investigate vaccine efficacy: For those developing CMV vaccines, peptides are essential for evaluating the immunogenicity of vaccine candidates.

Exploring the Market: Where to Buy CMV Peptides

The availability of CMV peptides for sale is crucial for researchers. Several reputable suppliers offer a range of CMV-related peptides, catering to diverse research needs. These often include:

* CMV (pp65) Peptide Pools: These are comprehensive mixtures of numerous peptides derived from the pp65 protein. For instance, a lyophilized mixture of 138 peptides from the 65 kDa phosphoprotein (pp65) of human cytomegalovirus (CMV; strain AD169) is available. These pools are designed to cover a broad spectrum of potential T-cell epitopes, offering a highly effective tool for studying immune responses to Human Cytomegalovirus (HCMV). Some pools, like the PepMix™ Human CMV (pp65), are specifically designed for this purpose. Another example is the STEMCELL Technologies CMV (pp65) Peptide Pool, a lyophilized mixture of 138 peptides. Similarly, Human cytomegalovirus (CMV) ImmuneSelect is a peptide pool composed of 37 peptides that cover MHC-I restricted epitopes of CMV.

* Specific CMV pp65 Epitope Peptides: Beyond pools, individual peptides representing specific, well-defined T-cell epitopes are also available. An example is the Human CMV pp65 (495-503) peptide, which is a specific sequence from the pp65 protein. These are often highly purified and characterized. For instance, an Antigen Peptide CMV pp65 - HLA-B\*0702 (TPRVTGGGAM) is a high-quality epitope peptide for stimulating antigen-specific T cells.

* CMV Sub Peptide Pools: These are curated pools of peptides, often focused on specific regions or classes of epitopes, such as those restricted by HLA class I. One such offering consists of 14 peptides, each corresponding to a defined HLA class I-restricted T cell epitope from cytomegalovirus (CMV).

* CMV Antigen: While not peptides themselves, CMV antigens are also available for sale, which can be used in various immunological assays. Researchers can buy high-quality Cmv Antigen online for metabolic research studies.

Key Considerations When Purchasing CMV Peptides

When sourcing CMV peptides for sale, several factors are critical for ensuring successful research outcomes:

* Purity: High purity is essential for reliable experimental results. Many suppliers offer peptides for sale with a purity of >95% or even >99% HPLC. Reputable companies will clearly state the purity of their products.

* Format and Quantity: Peptides are typically supplied in lyophilized powder form, which enhances stability. They are available in various quantities, from milligrams to larger bulk orders, depending on research needs. For example, some research peptides are offered at 99% purity and are synthesized and lyophilized in the US.
