Mouse anti α tubulin

Manufactured by Santa Cruz Biotechnology
Sourced in United States, Germany, Canada

Mouse anti-α-tubulin is a primary antibody that recognizes the α-tubulin subunit of the tubulin protein. Tubulin is a key structural component of microtubules, which are essential for various cellular processes such as cell division, intracellular transport, and cell motility. This antibody can be used for the detection and localization of α-tubulin in biological samples through techniques like immunofluorescence or Western blotting.

RNA from head skins was extracted using 0.5 ml of Trizol reagent (Invitrogen) according to the manufacturer’s protocol. RT-PCR was performed according to standard protocols using a reverse transcriptase kit and random primers (Promega). PCR products were size-fractionated by 2% agarose gel electrophoresis.

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.
