詳細
TSK-GEL G2000SWxlカラムは、GFCによる生体高分子分析用の高級カラムとして広く知られ、カラム単位体積当たりの微細孔容積が大きいこと、試料の吸着が少ないこと、およびカラム効率が高いことのすべてによって、他の追随を許さない試料分解能がもたらされます。5μmの粒子と125Åの微細孔を持つTSKgel G2000SWxlは、低分子タンパク質とペプチドの分離用として優れた選択肢です。分別範囲は、150,000 Daまでの球状タンパク質試料に適用されます。
物理的形状
Shipped in 0.05% NaN3 and 0.1 M Na2SO4 in 0.1 M phosphate buffer, pH 6.7.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 回答-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How can I determine the shelf life / expiration / retest date of this product?
1 回答-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
