In your brochure for Nitric Oxide and Cell Stress you present absorbance data from yeast lysis. How were the yeast prepared?
1 回答-
Here is the procedure as recommended by our Production group (March 2008): Grow S. cerevisiae (we used GP460 private strain) on YEPD medium; harvest cells by centrifugation. Wash the cells [7g] with 20 ml of 20 mM HEPES buffer, pH 7.0. Discard supernatant. Add 1 ml HEPES buffer to make a thick slurry and pour dropwise into liquid nitrogen. Take approx. 2 g of frozen pellet and homogenize with UltraTurrax T-25 while still in liquid nitrogen to make a fine powder. After all the liquid nitrogen has evaporated, take approximately 2 mL of HEPES buffer and add to the 2 g of finely powdered cells. Centrifuge for 5 min in an Eppendorf (benchtop) centrifuge at maximum speed. The supernatant liquid is the source of the enzyme. The total amount of protein received from this procedure was 21 mg (8.8 mg/mL in 2.4 mL total volume). We determined an activity of approximately 0.3 units/mL, using both the UV and DTNB assays.

Is Product GRSA, Glutathione Reductase Assay Kit, compatible with your CelLytic cell lysis reagents?
1 回答-
We have not tried using this kit with our CelLytic reagents. We believe it should be suitable for use with C2978 for mammalian cell lysis or C4882 for yeast cell lysis.

In your product bulletin you say you have tested Product GRSA, Glutathione Reductase Assay Kit, on rabbit reticulocyte lysate and Saccharomyces extract. Have you tested it on other species?
1 回答-
At this time, we have used the kit to test only these species. We have received inquiries concerning its use for rat and higher plant tissue, but we have no data at this time.

How does the storage temperature relate to shipping conditions?
1 回答-
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.
