CTW

English to Spanish Medical Medical: Pharmaceuticals
"The recovery of endotoxin load ranged from 103 to 121% and CTW (antigen diluent) did not influence the measured content of added endotoxins."

This text refers to vaccines indicated for the prevention of the diphtheria, tetanus, pertussis and poliomyelitis

Many thanks!!

solución reguladora/solución amortiguadora/tampón de carbonato con polisorbato/Tween®

CTW es, sin lugar a dudas, una solución reguladora/amortiguadora (o tampón). Es posible que se trate de solución reguladora de carbonato con polisorbato (Tween®), como en los siguienets casos:

«The precipitate or lyophilizate can be redissolved in a carbonate buffer having a molarity greater than 25 mM and a pH from 8.3 to 11.6, which can contain a detergent such as Tween 80 at a final concentration of about 0.05-0.5 weight percent, preferably a 100 mM carbonate buffer having a pH of 9.6 containing 0.05 weight percent Tween 80 (hereinafter called CTW buffer).»
http://www.freepatentsonline.com/4774086.html

«The supernatant was discarded; the pellet was dissolved in 1100 al CTW-buffer (0.286 g NaHCO3, 0.170 g Na2CO3, 50 Ill Tween-80, add to 50 ml MilliQ H20)»
En: http://www.wipo.int/pctdb/en/wo.jsp?IA=WO2005051985&wo=20050...

El término "tampón" se usa mucho en España, pero no en la Argentina, donde, en principio, es preferible emplear "solución reguladora" o "solución amortiguadora" (digo "en principio" porque acabo de encontrar la palabra "tampón" combinada con "pH" en 1 300 páginas web argentinas, mientras que "solución reguladora" y "solución amortiguadora" sólo figuran en 241 y 50 páginas, respectivamente).

Los polisorbatos son detergentes no iónicos, comercializados con la marca Tween. Desde el punto de vista químico, son ésteres de sorbitán polioxietilenado (un derivado del sorbitol) y ácido graso. Según el ácido graso esterificante, hay distintos tipos de polisorbato, los cuales se designan con diferentes cifras: polisorbato 20 (Tween® 20), polisorbato 40 (Tween® 40), etc.

No obstante, es aconsejable consultar con el cliente si CTW designa a este tampón o a otro.
Peer comment(s):

agree Tomás Cano Binder, BA, CT : Es posible que el cliente utilice "CTW" como nombre de producto. Un agree por la explicación detalladísima.

agree Detlef Aberle : Como muestra el primer ejemplo de María Claudia, CTW es la abreviación de Carbonate-Tween
