Anti rip3

Manufactured by Santa Cruz Biotechnology
Sourced in United States

Anti-RIP3 is a laboratory product that specifically binds to the RIP3 (receptor-interacting serine/threonine-protein kinase 3) protein. RIP3 is a key regulator of necroptosis, a form of programmed cell death. Anti-RIP3 can be used in research applications to study the role of RIP3 and necroptosis in various biological processes.

to manufacturer’s protocols (Thermo Scientific, TP-125-HL),
followed by incubation with diaminobenzidine (Thermo Scientific, TA-125-HD)
for 5 min to visualize immunolabeling. Following this, the cells were
washed using PBS and counterstained using Mayer’s hematoxylin
(Sigma-Aldrich, 1.07961.0100) for 1 min and mounted using a mounting
medium (Merck Millipore-107961, Germany). All specimens were then

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.
