Lactoferrin from Human Milk

Cat. No.: np001043

GRADE & PURITY BioReagent, Native, ≥95%(SDS-PAGE), Pre-lyophilization Protein Concentration: See COA

Accession #

P02788

Overview

Lactoferrin along with Secretory IgA can have a bacteriostatic effect in the intestinal tract of a breast fed newborn. Lactoferrin may also function as a promoter of iron absorption due to the high bioavailability of iron from digested Lactoferrin.

Prepared from human milk shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.

Frequently Asked Questions

What is the purity of this product, and how is it determined?

This product is supplied at ≥95% purity, determined by SDS-PAGE. Lot-specific values are stated on the Certificate of Analysis.

What does Native mean?

Native indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

How should this product be stored?

Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.

What does BioReagent mean?

BioReagent indicates that the product has been processed and tested for biological and biochemical applications. Specifications may include endotoxin limits, microbial controls, sterility, low DNase/RNase/protease activity, and verified biological activity where relevant.

How is this product shipped?

This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
