说明

Application

TES is a physiological Good′s buffer (pH 74.-7.9) used in biological research applications. It is often compared to other Good′s buffers for chemistry and optimal performance in a given system.

Other Notes

Hydrogen ion buffer for biological research; Suitable buffer for epidermal cell growth at pH 7.4-7.9 where additional buffering capacity is required

Facile cleavage of triethylsilyl (TES) ethers using o-iodoxybenzoic acid (IBX) without affecting tert-butyldimethylsilyl (TBS) ethers.

Yikang Wu et al.

Organic letters, 4(13), 2141-2144 (2002-06-21)

[reaction: see text] In DMSO cleavage of triethylsilyl (TES) ethers by o-iodoxybenzoic acid (IBX) was significantly faster than cleavage of tert-butyldimethylsilyl (TBS) ethers or further oxidation into carbonyl compounds. In most cases, TES protecting groups could be removed in good

A comparison of the frequency and type of chromosomal abnormalities in human sperm after different sperm capacitation conditions.

R H Martin et al.

Biology of reproduction, 47(2), 268-270 (1992-08-01)

Human sperm karyotypes can be prepared after fusion of human sperm with Golden hamster oocytes. Most laboratories use one of two methods of sperm capacitation: incubation of freshly-ejaculated sperm in Biggers, Whitten, and Whittingham (BWW) medium for 5-7 h at
