How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

How many units are present in the vial of Product G5035, Granulocyte-Macrophage Colony-Stimulating Factor human?
The ED50 was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is less than or equal to 0.1 ng/ml, corresponding to a specific activity of greater than or equal to 1 x 107 units/mg. So the 5 microgram package size (G5035-5UG) should have at least 50,000 units per vial.
There is no visible powder in the vial of Product G5035, Granulocyte-Macrophage Colony-Stimulating Factor human. Is the vial empty?
This product only contains 5 micrograms of protein without any carrier protein. The product is lyophilized from a small amount of solution so the product may not be visible in the vial.
Can I use Product G5035, Granulocyte-Macrophage Colony-Stimulating Factor human, on mouse cells?
There is only about 56% homology between human and mouse GM-CSF, and no cross-species activity. We would recommend to use mouse GM-CSF, Product No. G0282.
What is the isoelectric point (pI) for Product G5035, Granulocyte-Macrophage Colony-Stimulating Factor human?
The pI is 4.8.
