Sperm preparation media.
Sil-Select Plus™ is our home made new and improved gradient system for semen preparation.
Sil-Select Plus™ is a solution of silane-coated sicila particles in a chemically defined, balanced salts solution with HEPES (pH buffer).
Extensive testing during the design of the product has shown it to be non-cytotoxic and non-irritant with a non-significant allergenic potential.
Sil-Select Plus™ is produced from raw colloidal silica, so we have full control over each step in the production process. We have developed a very accurate purification system which results in a very clean product with endotoxin levels below 0.5EU/ml.
The Sil-Select Plus™ density gradient system (45%-90%) consists of a Sil-Select Plus Upper Layer (45%) and a Sil-Select Plus Lower Layer (90%).
We also offer Sil-Select Plus in an 80% dilution for use in IVF procedures.

Benefit |
HEPES (18 mM) |
HEPES stabilizes the pH under air (Clark and Swain 2014), therefore CO2 incubation is not required.
|
Earle’s Balanced Salt Solution (EBSS) |
The composition of the salt solution results in an optimum pH and osmolality environment for sperm cells.
|
Silane coated colloidal silica |
Density gradient media have been optimized for maximum efficiency in the selection of spermatozoa for use in ART. Their density is directly linked with their functionality and depends on the % silanized colloidal silica particles added in the media.
