MEL-JUSO Cells
General information
Description | One notable antigen, **MF116**, is a glycoprotein with a molecular weight of 105,000 and is shed by the cells into the culture medium. This antigen is expressed on several tumor cell lines, including ovarian, uterine, renal, and bladder carcinomas, but is absent from normal tissue sections. Another antigen, **MH94**, was detected on various carcinoma cell lines, including ovarian, uterine, colon, breast, lung, and cervical carcinomas. These markers have become important tools in cancer research, particularly for exploring how tumors express differentiation antigens and for the potential development of diagnostic or therapeutic approaches targeting these antigens【27†source】【28†source】. |

Required products
Phosphate-buffered saline (PBS) is a versatile buffer solution used in many biological and chemical applications, as well as tissue processing. Our PBS solution is formulated with high-quality ingredients to ensure a constant pH during experiments. The osmolarity and ion concentrations of our PBS solution are matched to those of the human body, making it isotonic and non-toxic to most cells.
Composition of our PBS Solution
Our PBS solution is a pH-adjusted blend of ultrapure-grade phosphate buffers and saline solutions. At a 1X working concentration, it contains 137 mM NaCl, 2.7 mM KCl, 8 mM Na2HPO4, and 2 mM KH2PO4. We have chosen this composition based on CSHL protocols and Molecular cloning by Sambrook, which are well-established standards in the research community.
Applications of our PBS Solution
Our PBS solution is ideal for a wide range of applications in biological research. Its isotonic and non-toxic properties make it perfect for substance dilution and cell container rinsing. Our PBS solution with EDTA can also be used to disengage attached and clumped cells. However, it is important to note that divalent metals such as zinc cannot be added to PBS as this may result in precipitation. In such cases, Good's buffers are recommended. Moreover, our PBS solution has been shown to be an acceptable alternative to viral transport medium for the transport and storage of RNA viruses, such as SARS-CoV-2.
Storage of our PBS Solution
Our PBS solution can be stored at room temperature, making it easy to use and access.
To sum up
In summary, our PBS solution is an essential component in many biological and chemical experiments. Its isotonic and non-toxic properties make it suitable for numerous applications, from cell culture to viral transport medium. By choosing our high-quality PBS solution, researchers can optimize their experiments and ensure accurate and reliable results.

Key features of Freeze Medium CM-1 include:
Broad Compatibility: Effective for a wide range of cell types, including primary cells, stem cells, and established cell lines.
High Viability: Optimized to maximize post-thaw cell recovery and viability, ensuring reliable experimental outcomes.
Ready-to-Use: Conveniently prepared and sterilized for immediate application, reducing preparation time and risk of contamination.
Enhanced Stability: Maintains consistent performance under standard cryopreservation conditions, ensuring reproducible results.
Long Shelf Life: CM-1 is a serum-containing, ready-to-use cryopreservation medium that can be stored in the refrigerator for up to one year.
Using CM-1 for Freezing Cells
To use CM-1 for freezing both adherent and suspension cells, follow these steps:
For adherent cells, wash and dissociate them from the culture substrate. For suspension cells, proceed directly to the next step.
Count the cells to ensure they are at the proper concentration.
Centrifuge the cells to pellet them, then resuspend in CM-1 freeze medium.
Transfer the resuspended cells into cryovials.
Use a slow-freezing method before transferring the cells to long-term storage.
