35s sodium sulfate

Manufactured by PerkinElmer

35S-sodium sulfate is a radioactive isotope of sodium sulfate that is commonly used as a tracer in various research applications. It emits beta radiation and has a half-life of approximately 87 days. The product is typically supplied as a solution and can be used to label or track the movement of sulfur-containing compounds in biological systems or other research experiments.

Quantitative Assessment of DS-epi1 Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
35S-sodium sulfate (1,500 Ci/mmol) was from PerkinElmer. Sulfate-free Dulbecco’s modified Eagle’s medium (DMEM) (AS31600 cat no. 074-91083P) was from Gibco. Superose 6 10/300, Superdex Peptide 10/300, PD-10 columns, Sephadex G-25, DEAE-Sephacel were from Cytiva. DS-epi1 was detected by Western blot with 1 μg/mL of an immunopurified anti-DS-epi1 rabbit polyclonal antibody obtained by immunization with the peptide antigen (KWSKYKHDLAAS, corresponding to amino acids 509 to 520 of the human/murine sequence; Innovagen, Sweden) (Maccarana et al. 2006 (link)). The Biorad stain-free gels were used, and both loading control, i.e. the blotted bands, and the chemioluminiscent signal were visualized with the ChemiDoc Imaging System (Biorad). Cell number was evaluated by DNA staining with crystal violet. Viability was assessed with PrestoBlue™ Cell Viability Reagent (Invitrogen).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
