10k amicon tubes

Manufactured by Merck Group

The 10K Amicon tubes are centrifugal filter devices designed for the concentration and purification of macromolecules, including proteins, peptides, and other biological samples. These tubes feature a 10,000 molecular weight cut-off (MWCO) membrane, which allows the passage of smaller molecules while retaining the desired larger molecules.

Fab Generation from IgG

Check if the same lab product or an alternative is used in the 5 most similar protocols
To generate the Fab from the IgG, a stop codon was inserted in the heavy chain constant region at “KSCDK”. The truncated heavy chains were co-transfected with the corresponding light chains in 293Expi cells to produce the Fabs. The supernatants were harvested 4 days post transfection. Fabs were purified with CaptureSelect CH1-XL MiniChrom Columns (#5943462005). Supernatants were loaded onto columns using an Econo Gradient Pump (Bio-Rad #7319001). Following a wash with 1x PBS, Fabs were eluted with 25 mL of 50 mM acetate (pH 4.0) and neutralized with 2 M Tris Base. The eluate was buffer exchanged with 1x PBS in 10K Amicon tubes (Millipore, UFC901008) and filtered with a 0.22 μm spin filter.

To generate the Fab from the IgG, a stop codon was inserted in the heavy chain constant region at “KSCDK”. The truncated heavy chains were co-transfected with the corresponding light chains in Expi293F (Life Technologies) cells to produce the Fabs. The supernatants were harvested 4 days post transfection. Fabs were purified with CaptureSelect CH1-XL MiniChrom Columns (#5943462005). Supernatants were loaded onto columns using an Econo Gradient Pump (Bio-Rad #7319001).

Fab Production from Truncated IgG

Check if the same lab product or an alternative is used in the 5 most similar protocols
To generate the Fab of an IgG, a stop codon was inserted in the heavy chain constant region at “KSCDK*.” The truncated heavy chains were cotransfected with the corresponding light chains in Expi293 cells to produce the Fab. The supernatants were harvested 4 days after transfection. Fabs were purified with CaptureSelect CH1-XL MiniChrom Columns (#5943462005). Supernatants were loaded onto columns using an Econo Gradient Pump (Bio-Rad, #7319001). After a wash with 1× PBS, Fabs were eluted with 25 ml of 50 mM acetate (pH 4.0) and neutralized with 2 M tris base. The eluate was buffer-exchanged with 1× PBS in 10K Amicon tubes (Millipore, UFC901008) and filtered with a 0.22-μm spin filter.

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.
