## Abstract

The method described herein reduces the amount of aggregating metal released into solutions of Interferon-β.

## Claims

### Claim 1

A method for storing and delivering solutions of an Interferon-β comprising:
providing a device including a housing, wherein the housing comprises an aggregating metal;

### Claim 11 (depends on 1)

The method of claim 1, wherein the housing releases a concentration of the aggregating metal of less than about 50 parts per billion.

### Claim 12 (depends on 1)

The method of claim 1, wherein the aggregating metal is selected from the group consisting of iron, copper, nickel, molybdenum and tungsten.

### Claim 13 (depends on 12)

The method of claim 12, wherein the aggregating metal is tungsten.

### Claim 14 (depends on 1)

The method of claim 1, wherein the device is a syringe, bottle, vial or a bag.

### Claim 15 (depends on 14)

The method of claim 14, wherein the device is a syringe.

### Claim 16 (depends on 1)

The method of claim 1, wherein the housing of the device is constructed of glass, metal or plastic.

### Claim 17 (depends on 16)

The method of claim 16, wherein the housing is constructed of glass.
