blotting
吸い取り
解説 Definition
blotting は blot(吸い取る、しみをつける)の動名詞・現在分詞で、名詞としてはインクや液体を吸い取ることという意味です。紙や布で余分な水分を取る場面や、実験で物質を膜に移す技法にも使われます。
Blotting is the act of absorbing or removing ink, oil, moisture, or another liquid by pressing paper or cloth against it. In laboratory work, it can also mean transferring proteins, DNA, or RNA onto a membrane for analysis.
覚え方のコツ Memory Tip
blotting は原形 blot「液体を吸い取る、しみを付ける」に -ing を付けた形。短母音+子音で終わるため t を重ねて blotting となり、発音も原形の /t/ を保つ。blotting paper「吸い取り紙」や blotting excess oil「余分な油を吸い取ること」で覚え、実験では膜への転写も指す。
Start with the verb blot, meaning to absorb liquid by pressing a material onto it or to make a stain. Because blot ends in a stressed short vowel followed by one consonant, the final t doubles before -ing: blot becomes blotting. Picture blotting wet ink with blotting paper or blotting excess oil with a cloth. In biology laboratories, the same core idea extends to transferring proteins or nucleic acids onto a membrane, as in Western or Southern blotting.

blotting の語源・成り立ち Etymology
中英語 blot(しみ)はおそらく古ノルド語 blottr に由来。インクのしみを吸い取る動作から blotting paper(吸い取り紙)が生まれた。関連語:blot, blotter。「しみ」という原義が「しみを除去する・吸い取る」行為へと転じた語。
Blotting is the -ing form of blot. The noun blot, meaning a spot or stain, entered Middle English and is often connected with a Scandinavian source, although its precise early history is not completely certain. The verb developed senses including making a stain and removing excess liquid by pressing absorbent material against it. This latter action produced the expression blotting paper. Scientific uses later extended the idea to transferring biological material onto a membrane.
