Thymalin (25mg) – Premium Research Peptide for Immunology Studies

Welcome to Liaocheng Yixin Company, your trusted source for premium thymalin 25mg for research. As a specialized peptide synthesis manufacturer operating from our facility at No. 9 Lushan Road, Dongcheng Street, Liaocheng Economic and Technological Development Zone, Shandong Province, we provide high-quality research compounds for the global scientific community.

Thymalin is a polypeptide complex isolated from the thymus gland that regulates immune system functions . It has demonstrated efficacy in a wide range of immunology research applications and is known for its ability to restore immune balance, regulate T- and B-lymphocyte populations, and stimulate cellular immune responses . Our thymalin 25mg for research offers investigators a reliable, high-purity compound for immunology and regenerative research.

What is Thymalin?

Thymalin (CAS: 63958-90-7) is a polypeptide complex derived from the thymus that functions as an immunomodulatory peptide . It belongs to the group of drugs that epigenetically regulate gene expression and synthesis of immunogenesis proteins . Thymalin normalizes differentiation, proliferation, and reduces apoptosis of lymphoid cells.

Key identifiers:

• CAS Number: 63958-90-7

• Molecular Formula: C33H54N12O15

• Molecular Weight: 858.85 g/mol 

• Synonyms: Thymulin, Serum Thymic Factor

• Purity: ≥99% verified by HPLC

Mechanism of Action in Research

Thymalin exerts its immunomodulatory effects through multiple mechanisms:

Molecular Mechanism

Thymalin contains active short peptides—EW, KE, and EDP—that can penetrate the cell nucleus and nucleolus to bind to specific DNA sequences and/or histone proteins . This binding results in changes in gene expression and the synthesis of key proteins involved in immune function .

Immunomodulatory Effects

• Regulates gene expression: Influences the synthesis of heat shock proteins, cytokines, and proteins involved in immune cell differentiation 

• Stimulates stem cell differentiation: Activates hematopoietic stem cell differentiation into immune cells 

• Modulates cytokine production: Reduces synthesis of pro-inflammatory cytokines such as IL-1ß, IL-6, and TNF-α by 1.4-6.0 times in human peripheral blood mononuclear cells 

• Normalizes lymphocyte populations: Restores CD4+, CD8+, and CD28+ lymphocyte counts and function 

Scientific Research Applications

Thymalin has been extensively studied across multiple research domains:

Immunology Research

A meta-analysis of randomized controlled studies demonstrated that Thymalin administration resulted in a statistically significant increase in reduced T-lymphocyte counts compared to control groups. The effect size was classified as “large” (SMD > 0.8) . Thymalin has been shown to:

• Restore immunity and regulate T- and B-lymphocyte populations

• Stimulate cellular immune responses and increase phagocytosis

• Enhance regeneration and hemopoiesis processes 

Infectious Disease Research

Thymalin has demonstrated efficacy in research models of various infectious diseases:

• COVID-19 research: Thymalin reduced hospital mortality in older patients with severe COVID-19 by half 

• Viral infection models: Shown effectiveness in hepatitis A and B, erysipelas, meningococcal infection, and typhoid fever models 

• Respiratory infection research: Reduced acute respiratory infections in senior patients by 2.0-2.4-fold 

Inflammatory Research

Thymalin has been studied for its ability to prevent “cytokine storm” by reducing pro-inflammatory cytokines IL-1α, IL-6, IL-8, and TNF-α . It also reduces the intensity of intravascular blood coagulation, which is a common complication in severe inflammatory states .

Regenerative and Gerontology Research

A 6-8 year clinical study of 266 elderly patients showed:

• Thymalin treatment resulted in a 2.0-2.1-fold decrease in mortality rate

• Combination with Epithalamin achieved 2.5-fold reduction in mortality

• Annual combination treatment for 6 years reduced mortality by 4.1 times 

Bone and Tissue Regeneration Research

Recent studies have investigated Thymalin in bone defect healing. Research demonstrated that Thymalin injection into surrounding soft tissues affected T-lymphocyte, B-lymphocyte, and macrophage expression in post-traumatic mandible regenerate models .
