Chitin Extraction from Red Snow Crabs

Check if the same lab product or an alternative is used in the 5 most similar protocols

Crab shells were collected from red snow crabs (genus Chionoecetes) in Teradomari, Niigata, Japan. All chemicals used in the preparation of chitin were of analytical grade. Hydrochloric acid (HCl), sodium hydroxide (NaOH), potassium hydroxide (KOH), N,N-dimethyl acetamine (DMAc), lithium chloride (LiCl), and ethanol were products of Nacalai Tesque, Inc. (Tokyo, Japan). Prior to the use of DMAc, the solvent was stored with KOH for over 5 days, and LiCl was dried in vacuum oven at 80 °C for 24 h to remove trace of moisture.

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.
