Gene Information

human ... RAF1(5894)

Application

Raf-1 is a serine/threonine protein kinase which is involved in the MAPK signal transduction pathway, a pathway that is involved in the development and progression of cancer. Raf-1 kinases are used to study potential cancer treatments as well as the responses to cancer treatments .

Biochem/physiol Actions

Raf-1 activates the protein kinases MEK1 and MEK2. MEK1 and MEK2 are phosphorylated to activate protein kinases ERK1 and ERK2. Activated ERKs play an important role in cell division, apoptosis, cell differentiation, and cell migration .

Unit Definition

One unit will activate MEK B substrate by 10% per min at pH 7.0 at 30 °C.

Physical form

Solution in 50 mM Tris-HCl, pH 7.0 buffer containing 14 mM β-mercaptoethanol, 1 mM benzamidine, 0.1 mM PMSF, 1 mM EDTA, and 10% glycerol.

  1. 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.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
