Psoriasis Skin Punch Biopsy
About:Psoriasis Skin Punch Biopsy samples are obtained from donors clinically diagnosed with psoriasis and provide tissue for studying epidermal hyperproliferation, immune infiltration, and cytokine dysregulation in psoriatic lesions.
About Psoriasis Skin Punch Biopsy
Psoriasis Skin Punch Biopsy for Research
Psoriasis Skin Punch Biopsy samples are collected from clinically confirmed psoriasis donors by licensed clinicians. Buy or purchase psoriasis skin biopsy tissue in fresh or frozen formats — pricing and current availability on request.
Why Lesional Tissue Matters in Psoriasis
Psoriasis is a chronic immune-mediated skin disease driven by the IL-23/Th17 axis, and the pathology is visible in tissue in a way it is not in blood. A plaque biopsy shows the defining histology directly: epidermal hyperproliferation with acanthosis, parakeratosis and loss of the granular layer, elongated rete ridges, dilated dermal capillaries, and a mixed infiltrate of T cells, dendritic cells and neutrophils — including the Munro microabscesses characteristic of the disease.
That makes skin punch biopsies the primary material for target validation in psoriasis, particularly for the IL-17 and IL-23 pathways underlying current biologics. Because uninvolved skin from the same donor is genetically identical but phenotypically normal, paired lesional and non-lesional sampling is the strongest available design — it controls for donor genetics entirely and isolates the disease signal.
Sample and Donor Stratification
- Paired sampling — lesional plaque plus adjacent non-lesional or sun-protected skin from the same donor
- Disease severity — PASI and BSA scores where recorded
- Psoriasis subtype — plaque, guttate, inverse, pustular, or erythrodermic
- Lesion site — elbow, knee, scalp, trunk; scalp and nail involvement noted where present
- Treatment status — treatment-naive, topical-only, or on systemic/biologic therapy (anti-TNF, anti-IL-17, anti-IL-23)
- Comorbidity — concurrent psoriatic arthritis where diagnosed
- Punch diameter specified to your protocol; FFPE, OCT, or RNAlater preservation available

What is the turnaround time for custom collections?
Timelines depend on condition, sample type, and I/E criteria but we often start collection within 2 weeks of signed agreement.
Do you have samples in stock?
YES - we have in-stock inventory. You can also email us at learnmore@sanguinebio.com as we continually get new samples in our inventory.
What does unique donor mean?
Each sample from a different individual - Unique donor means each sample comes from a different person, ensuring biological diversity in your study.
Are samples collected under IRB-approved protocols?
YES - "IRB-approved collection protocols" and IRB approval documentation available upon request. Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval.
