Sephadex g 100

Manufactured by Merck Group
Sourced in United States, Germany, China

Sephadex G-100 is a size-exclusion chromatography media used for the separation and purification of molecules based on their size and molecular weight. It is a porous, cross-linked dextran gel that allows smaller molecules to penetrate the pores while larger molecules are excluded, enabling their separation. Sephadex G-100 is commonly used in various applications such as protein purification, desalting, and molecular weight determination.

Purification and Sequencing of Endpoint RT-PCR Products

Check if the same lab product or an alternative is used in the 5 most similar protocols
We purified the endpoint RT-PCR products with Sephadex® G-100 (Sigma-Aldrich, St. Louis, MO, USA) columns by centrifugation at 770×g for 3 min and then prepared the sequencing reactions with the BigDye® Terminator v3.1 Cycle Sequencing Kit (Applied Biosystems). The sequencing reactions had a final volume of 10 μl containing 1 μl BigDye® Terminator v3.1 Ready Reaction Mix, 1.5 μl 5× Sequencing Buffer, 0.2 μM of either the forward (FS778) or the reverse (cFD2) primer and 3 to 10 ng cDNA. The temperature profiles were as follows: 1 min at 96 °C, followed by 25 cycles of 10 s at 96 °C, 5 s at 50 °C and 4 min at 60 °C. We then purified the sequencing products with Sephadex® G-50 (Sigma-Aldrich) columns by centrifugation at 770×g for 3 min and mixing with 5 μl of HiDi Formamide (Applied Biosystems) and sequenced the prepared cDNA in both directions on an Applied Biosystems 3500 Genetic Analyser (Applied Biosystems). We examined the sequences with the MEGA6 Software [37 (link)] and compared them against the BLAST Nucleotide database [38 (link), 39 ].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
