Description

Reliable intestinal organoid establishment begins with the recovery of intact, viable intestinal crypts. During conventional intestinal tissue digestion, insufficient dissociation can leave crypts trapped within the mucosa, while excessive enzymatic or mechanical treatment may disrupt crypt architecture and reduce the ability of intestinal stem cell-containing units to initiate new organoids.

XR Organoid Intestinal Digestion Solution is an optimized intestinal tissue digestion solution developed for controlled dissociation of adult or mouse intestinal tissue. The formulation is designed to release structurally intact crypt units from intestinal mucosal tissue while minimizing unnecessary digestion-related stress and damage.

This ready-to-use intestinal crypt isolation solution supports the preparation of small intestinal and colonic crypts for downstream intestinal organoid culture. Under the documented workflow, tissue is digested at 4°C and requires only gentle pipetting after digestion, helping researchers recover crypts suitable for embedding in an appropriate extracellular matrix and culture in a compatible intestinal organoid medium.

How It Works

Intestinal crypt isolation requires separation of epithelial crypt structures from surrounding mucosal tissue without unnecessarily breaking the recovered units into dispersed single cells. XR Organoid Intestinal Digestion Solution is formulated to support this balance through a controlled intestinal tissue dissociation workflow.

After the intestinal sample has been cleaned and cut into small fragments, the tissue is incubated with the digestion solution at 4°C. Gentle pipetting following digestion helps release crypt structures. The suspension is then filtered and centrifuged to collect the recovered crypt-containing fraction for downstream organoid culture.

Important: The documented 25–30 minute digestion period is a reference condition. Intestinal region, tissue thickness, sample source and fragment size may affect dissociation efficiency. Monitor crypt release and avoid excessive mechanical pipetting or prolonged digestion.

Recommended Workflow

Clean the intestinal tissue and cut it into approximately 1 mm × 1 mm fragments.
Add 10 mL of precooled PBS and agitate the tube to wash the intestinal fragments and remove intestinal contents.
Repeat the PBS washing process three times.
Add 10 mL of XR Organoid Intestinal Digestion Solution.
Digest the tissue on a shaker at 4°C for approximately 25 minutes.
Remove the digestion solution after incubation.
Add 5 mL of an appropriate termination solution to stop digestion.
Gently pipette the digested intestinal fragments using a 5 mL pipette.
Filter the tissue suspension through a 70 μm cell strainer.
Centrifuge at 300 × g for 5 minutes and remove the supernatant.
Process the recovered crypt fraction using the appropriate matrix and intestinal organoid culture medium for the intended workflow.

Workflow note: The termination solution, extracellular matrix and intestinal organoid culture medium are separate workflow components unless specifically stated in the ordering information.

Performance Data

Small Intestinal and Colonic Crypt Recovery

Under the documented test conditions, intestinal tissue was digested at 4°C for approximately 25–30 minutes. Following gentle pipetting with a 5 mL pipette, crypt structures could be recovered from both small intestinal and colonic tissue samples.

The recovered crypts showed preserved structural integrity under the evaluated conditions. The product documentation indicates that the isolated crypts can be combined with a corresponding organoid culture medium and matrix to support subsequent intestinal organoid formation.

Why Use an Intestinal-Specific Digestion Solution?

General-purpose tissue dissociation reagents may not provide the level of control required for intestinal crypt extraction. A digestion condition that is too weak may produce low crypt recovery, while overly aggressive treatment may fragment crypts, increase cellular stress and compromise downstream organoid formation.

XR Organoid Intestinal Digestion Solution is optimized around the specific requirement to separate crypt structures from intestinal mucosa while maintaining their overall architecture. Its low-temperature workflow and limited mechanical handling help researchers standardize a critical early step in intestinal organoid culture.

By combining targeted intestinal tissue dissociation with gentle crypt recovery, the solution is suitable for laboratories seeking a more controlled approach to small intestinal and colon organoid sample preparation.

Factors That Can Affect Crypt Isolation

Tissue fragment size: Uneven or oversized fragments may digest inconsistently.
Intestinal region: Small intestinal and colonic tissues may differ in dissociation behavior.
Sample condition: Collection method, storage time and tissue condition may influence crypt recovery.
Digestion duration: Insufficient incubation may reduce release, while excessive digestion may damage crypt structures.
Mechanical force: Vigorous or repeated pipetting may disrupt intact crypts.
Temperature control: The documented workflow uses digestion at 4°C and should not be assumed to perform identically at other temperatures.
Downstream culture system: Organoid formation also depends on matrix selection, culture medium, seeding density and sample quality.

FAQ

What is XR Organoid Intestinal Digestion Solution used for?

XR Organoid Intestinal Digestion Solution is used for controlled intestinal tissue digestion and the isolation of crypt structures from adult or mouse intestinal tissue before intestinal organoid culture.

Is this product an intestinal crypt isolation reagent?

Yes. It is specifically optimized as an intestinal crypt isolation solution that helps release intact crypt units from intestinal mucosal tissue under the documented low-temperature digestion workflow.

Can this solution be used for small intestinal crypt isolation?

Yes. The product documentation includes recovery results for small intestinal crypts following digestion at 4°C and gentle pipetting.

Can it be used for colon crypt isolation?

Yes. The documented applications and performance images include the isolation of colonic crypts from intestinal tissue.

Is the product suitable for mouse intestinal organoid culture?

Yes. The product is described for adult or mouse intestinal tissue samples and can be used during the crypt isolation stage of a mouse intestinal organoid culture workflow.

Can it be used with adult intestinal tissue?

Yes. The product documentation describes its use with adult intestinal tissue. Digestion conditions should still be monitored and optimized according to tissue source, intestinal region and sample condition.

Does the solution dissociate intestinal tissue into single cells?

The documented workflow is intended primarily to release intact crypt units rather than completely dissociate the sample into a single-cell suspension. The final outcome may vary with digestion time and mechanical handling.

Why is intestinal crypt integrity important for organoid culture?

Intact crypt units contain the epithelial compartment required to initiate intestinal organoid growth. Excessive digestion or vigorous pipetting may disrupt crypt architecture and reduce the quality of the recovered starting material.

What digestion temperature is recommended?

The documented workflow uses digestion at 4°C on a shaker. The product should not be assumed to provide the same results at other temperatures without additional optimization.

How long should intestinal tissue be digested?

The documented workflow uses approximately 25 minutes, while the performance notes describe a 25–30 minute range. The actual endpoint should be determined by monitoring crypt release and the condition of the tissue.

How much digestion solution is used in the documented workflow?

The provided procedure uses 10 mL of intestinal digestion solution for the prepared intestinal tissue fragments. Appropriate volume may depend on tissue quantity and vessel size.

Is mechanical dissociation required after digestion?

Yes. The documented workflow uses gentle pipetting with a 5 mL pipette after digestion. Excessive pipetting should be avoided because it may damage crypt structures.

What cell strainer is used after intestinal tissue digestion?

The documented protocol uses a 70 μm cell strainer to filter the digested tissue suspension before centrifugation.
