Transfer Factor

Synonimy: Transfer Factor, Dialyzable Leukocyte Extract, DLE, Transfer Factor Polypeptide, Bovine Transfer Factor, 253764-88-4

Transfer Factor is a low-molecular-weight polypeptide fraction derived from bovine colostrum or leukocyte extracts, standardized for use in immune-support formulations. Buyers source it for capsule, tablet, and powder blend applications where a well-defined protein fraction is required.

The material is supplied as an off-white to light yellow powder, typically standardized by HPLC to a polypeptide content of 90% or higher. Each lot is produced under controlled conditions to ensure consistent molecular weight distribution and solubility, critical for reproducible formulations.

For formulators, transfer factor integrates easily into dry blends and aqueous systems. Its water solubility allows for flexible dosing in capsules, stick packs, and functional beverages. We recommend storing the powder in a cool, dry place away from direct light to maintain stability.

Grade & Supply Forms

We offer transfer factor in a standard food-grade form, with polypeptide content verified by HPLC. The powder is milled to a fine particle size to facilitate blending and is available in bulk quantities. Custom particle sizes and concentrations can be arranged upon request.

Applications & Formulation Use

Transfer factor is commonly used in dietary supplements aimed at immune support, including capsules, tablets, and powder mixes. It also finds use in pet nutrition and specialized functional foods. In formulations, it is typically combined with other immune-support ingredients such as beta-glucans or vitamin C.
