Cryoprotectants

6''-O-Acetylastragalin
Catalog No: CFN99281

Kaempferol 7-O-beta-d-glucopyranoside (6''-O-Acetylastragalin) is a novel supercoolant, to sub-zero non-freezing rat heart preservation.

Hypotaurine
Catalog No: CFN00019

Hypotaurine is a precursor of taurine and an antioxidant, intracellular hypotaurine is mainly supplied to placental trophoblasts by transfer from extracellular fluid across the plasma membrane, and may play a role in cell protection by scavenging reactive oxygen species. Hypotaurine also suppresses acute, inflammatory, and neuropathic pain, may regulate nociceptive transmission physiologically by activating glycinergic neurons in the spinal cord, is a promising candidate for treating various pain states.Hypotaurine/taurine synthesis strongly inhibits cysteinesulfinate decarboxylase (pyridoxal 5'-phosphate-dependent enzyme) as well as cystathionine γ-lyase. Hypotaurine and raffinose supplementation in semen extenders provide a protection of sperm parameters against cryopreservation injury.

(-)-Epigallocatechin-3-(3''-O-methyl) gallate
Catalog No: CFN92081

(-)-Epigallocatechin-3-(3''-O-methyl)gallate shows antioxidative, cytotoxic, antiallergic, and anti-inflammatory activities, it can negatively regulate basophil activation through the suppression of FcepsilonRI expression. Epigallocatechin-3-(3''-O-methyl)gallate has the function for cold preservation of primary rat hepatocytes.
