Supply Copper Peptide 100mg/Vial Skincare Powder Cosmetics Peptide GHK-Cu for Anti-allergic & Skin
Product Description GHK|GHK-Cu|Copper Peptide Cosmetics Peptide for Anti-Wrinkles CAS NO:49557-75-7 Specification:100mg/vial Sequence: Gly-His-Lys(Cu2+) Molecular Formula: C28H46N12O8Cu Molecular Weight: 742.29 Appearance: Lyophilized white powder Purity: 99.0%min.(HPLC) Lead time: 3-5days Mini Order: 10vials Packaging: 10vials/kit . Product Specification / Models GHK Copper peptide GHK-Cu is a naturally occurring human tri-peptide. In plasma, the level of GHK-Cu is about 200 ng/ml at age 20. By the age of 60, the level drops to 80 ng/ml. Scientific studies conducted in different research laboratories around the world have established that human tri-peptide GHK-Cu possesses a plethora of biological actions including activation of wound healing, attraction of immune cells, antioxidant and anti-inflammatory effects, stimulation of collagen and glycosaminoglycan synthesis in skin fibroblasts and promotion of blood vessels growth. Recent studies indicate its important role in stem cell biology and anti-tumor defense. Since GHK-Cu plays an important role in skin biology, it is widely used in cosmetics as a reparative and anti-aging ingredient.
Introduction:
4-hydroxyethyl piperazine ethosulfonic acid (HEPES) is an important hydrogen ion buffer, which has a good buffer ability in the pH range of 6.8 to 8.2, and can control a constant pH for a long time. Using a concentration of 10 ~ 50mmol/L, the general culture medium containing 20mmol/L 4-hydroxyethyl piperazine taurine can have a good buffer capacity, and has no toxic effect on cells.
Application:
HEPES (4-hydroxyethyl piperazinethesulfonic acid) is a non-ionic amphoteric buffer with high polarity, and is inert to a variety of chemical reagents and enzymes. It does not participate in and interfere with the process of biochemical reactions, and has no inhibitory effect on enzyme chemical reactions. Therefore, it can be used specifically for the research of proteins and enzymes that are highly volatile and ph-sensitive to organelles and very volatile.
Buffer solution preparation:
(1)hepes buffer can be directly added to the prepared culture medium according to the desired concentration, and then filtered to remove bacteria. 2.38 g HEPES was added to each 1000ml of culture medium, the pH was adjusted to 7.2 with lNNaOH after dissolution, and the bacteria were removed by filtration before use. At this time, the concentration of HEPES was 10mmol/L.
(2) 100x storage solution (lmol/L) could also be prepared. Before use, 99ml culture solution was added to lml storage solution, and the final concentration was 10mmol/L. lmol/L (100x) hepes buffer was prepared as follows: 23.8gHEPES was dissolved in 90ml double distilled water, the pH was adjusted to 7.5-8.0 with lNNaOH, and then the water was fixed to 100ml, filtered to remove bacteria, divided into vials (2ml/ bottle), and stored at 4�ºC or -20�ºC.
Purpose:
1.Biological buffer; Reaction buffer, prehybridization buffer and hybridization buffer for isolation and analysis of RNA nuclear fraction; For RNA with T4RNA
2.Molecular biology grade is used for RNA3' -end labeling with T4 RNA ligase
3.Cell-cell adhesion, short-term cell aggregation culture, cleaning of tissue and cell buffer
