Perk1 2 and erk1 2 antibodies

Manufactured by Cell Signaling Technology

The PERK1/2 and ERK1/2 antibodies are laboratory reagents designed for the detection and analysis of their respective target proteins in biological samples. These antibodies are specific for the phosphorylated forms of PERK1/2 and ERK1/2, which play key roles in cellular signaling pathways. The core function of these antibodies is to enable researchers to study the activation and regulation of these important signaling proteins.

Generation of Anti-PIPKIγ Antibodies

Check if the same lab product or an alternative is used in the 5 most similar protocols
Polyclonal PIPKIγ anti-serum was generated by immunizing rabbits using purified His-tagged mouse PIPKIγ and purified using a human PIPKIγ-conjugated affinity column to generate the anti-pan-PIPKIγ antibody as described 9 (link). To generate the phosphorylated-PIPKIγ antibody, we immunized rabbits with a PIPKIγ phosphopeptide (CDIpYFPTDERSWVYSPLHYSA). The anti-sera were collected, pre-cleaned by a non-phosphopeptide (CDIYFPTDERSWVYSPLHYSA) affinity column, then purified using an affinity column conjugated with the phosphopeptide. Antibodies: anti-HA and MMP9 antibodies (Millipore, Billerica, MA); pERK1/2 and ERK1/2 antibodies (Cell Signaling, Danvers, MA); β-actin antibody and monoclonal anti-α smooth muscle actin antibody (Sigma, St. Louis, MO); Rabbit anti-Cytokeratin 8 antibody, Rat monoclonal anti-CD34 antibody and monoclonal anti-CD68 antibody (Abcam, Cambridge, MA); Alexa Fluor 488 goat anti-mouse antibody, Alexa Fluor 555 goat anti-rabbit antibody and Alexa Fluor 555 goat anti-rat antibody (Molecular probes).

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.
