What polypropylene column should the we use according to the protocol to wash the resin prior to use?
1 回答-
For washing the resin prior to use, the customer can use the following options:
1. C2603 Mini-Columns: These have a capacity of 0.5 mL and an overall height of 1.9 inches.
2. C2728 Mini-Columns: These have a capacity of 2.4 mL and an overall height of 1.5 inches.
The washing procedure using Polymyxin B Agarose (Product No. P1411) can be carried out in a column or in a batch method. For a column, the customer can use disposable mini columns, such as Product Nos. C2603 (0.5 ml) and C2728 (5.0 ml). If a larger column is needed, the customer can use a polypropylene syringe barrel or use the batch method.
In the batch method, the solution is incubated with the polymyxin B agarose for a minimum of 30 minutes with rotation in either a 15 ml or 50 ml polypropylene tube. The tube is then centrifuged, and the supernatant contains the protein of interest with decreased endotoxin that has been bound to the beads and pelleted in the tube.

What methods can be used to remove endotoxin from a product?
1 回答-
The product is not tested for endotoxin; however, P1411 may be used to strip endotoxin. The P1411 datasheet includes a suggested protocol for this process. The protocol involves washing the resin, equilibrating the column, dissolving the sample in buffer, eluting with endotoxin-free buffer, and collecting the fractions. The collected fractions containing the protein should then be lyophilized. The polymyxin B agarose can be regenerated at least 10 times, and the resin can be stored in 25% ethanol at 4°C
