This product consists of 12 highly purified and prestained proteins ranging in molecular weight from 10 kDa to 245 kDa, among them, 72 kDa is orange band, 25 kDa is green band, 10/15/20/35/ 45/60/100/140/180/245 kDa are blue bands, the protein concentration of each band was about 0.1-0.4 mg/mL. Using this product, the state of protein

electrophoresis and the effect of membrane transfer can be dynamically observed. After SDS-PAGE electrophoresis,

the color bands were transferred to PVDF membrane and NC membrane. This product is conveniently packaged

and is a ready-to-use product, do not heat, dilute or add reducing agents!

After the prestained protein is combined with the dye, the molecular weight will change in the gel of different

concentrations. This product is only for reference when judging the molecular weight of the target protein.

Instructions

1. After the product is thawed at room temperature,mix gently to fully dissolve the precipitate.

2. Then take an appropriate amount of this product into the gel hole. mini-gel: 3-5 μL; when the thickness of the gel is greater than 1.5 mm or the macromolecular bands need to be deepened, the loading volume can be appropriately increased: 5-10 μL.

Notes

1. The product needs to be returned to room temperature before use to fully dissolve the precipitate. Incomplete protein denaturation at low temperature may lead to different degrees of dispersion of electrophoresis bands.

2. In western blot experiments, large proteins (>100 kDa) in the product may require longer transfer times or higher transfer voltages to complete transfer.

3. This product contains SDS, and the protein has been denatured, so it should not be used as a molecular weight reference standard for natural protein molecular electrophoresis.

4. The product will have deviations in protein size under different electrophoresis conditions, but after they are calibrated by non-prestained protein standards in the same buffer system, they can be used for protein determination of similar molecular weights.

5. At low concentration of gel, low molecular weight protein will swim on the dye front.

FAQ

Q: Why did the product exhibit varying degrees of deviation when applying the glue?

A: The pre-stained protein Marker shifts its position in different electrophoresis systems. These shifts are for reference only. Since the dye binds to the protein, it usually moves faster than the original protein in most cases. We have calibrated this with non-pre-stained Markers. For example, the 180KD band from some manufacturers appears at 140KD in the Bis-Tris system, while our 180KD band in the same system actually reaches 175KD. This proves that our shift is smaller. The reference diagram is as follows:

Q: Are the proteins labeled with pre-dyed markers? If so, what kind of label is used?

A: We have removed the "His" label without any tags.

Ceturegel™ Matrix LDEV-Free -40183ES

5 mL $93 ~~$155~~
10 mL $285 ~~$171~~

Ceturegel™ Matrix LDEV-Free Matrix is a soluble basement membrane preparation extracted from EHS mouse tumors rich in extracellular matrix proteins. Its main components are laminin, type IV collagen, heparan sulfate proteoglycan (HSPG), and nestin as well as growth factors such as TGF-beta, EGF, IGF, FGF, tissue plasminogen activator, and other growth factors contained in EHS tumors. At room temperature, it aggregates to form a biologically active three-dimensional matrix, which simulates the structure, composition, physical properties, and functions of the cell basement membrane in vivo, which is beneficial to the culture and differentiation of cells in vitro. It can be used for studies of cell morphology, biochemical function, migration, invasion, and gene expression.

The three-dimensional culture matrix formed by Matrix can promote the adherence and differentiation of epithelial cells, hepatocytes, sertoli cells, melanoma cells, vascular endothelial cells, thyroid cells, and hair follicle cells. Ceturegel™ Matrix can affect gene expression in three-dimensional cultures of murine hepatocytes and human mammary epithelial cells. At the same time, Ceturegel^TM Matrix can be used as a basic scaffold for various tumor cell invasion studies using matrigel, an essential matrix for in vitro and in vivo studies of angiogenesis, and a three-dimensional scaffold for the growth of transplanted tumor cells in in vivo animal models. Ceturegel™ Matrix also supports the regeneration of peripheral nerves and the differentiation of bovine fallopian tube epithelial cells.

YEASEN Matrix is a sterile product with a concentration of 8~20 mg/mL, which meets a variety of experimental requirements, including angiogenesis studies and tumor cell migration.
