Goat anti hes1

Manufactured by Santa Cruz Biotechnology

Goat anti-Hes1 is a polyclonal antibody produced in goats that recognizes the Hes1 (Hairy and Enhancer of Split 1) protein. Hes1 is a basic helix-loop-helix (bHLH) transcriptional repressor that plays a role in the Notch signaling pathway and in the regulation of various cellular processes. The Goat anti-Hes1 antibody can be used to detect and study the Hes1 protein in various applications, such as Western blotting, immunohistochemistry, and immunofluorescence.

Western Blot Protein Analysis Protocol

The protein content of cell extracts or tissue prepared in radioimmunoprecipitation assay lysis buffer was determined using the Bradford protein assay kit (Bio-Rad). About 30 μg of proteins were separated by SDS-polyacrylamide gel electrophoresis. After transferring to nitrocellulose membranes, immunoblots were probed separately with various primary antibodies. Subsequently, the immunoblots were blocked with 5% skimmed milk in Tris-buffered saline solution. Fluorescently labeled or horseradish peroxidase–conjugated secondary antibodies were detected by the Odyssey Infrared Imaging System (LI-COR Biosciences). Primary antibodies were used as following: rabbit anti-JMJD3 (Millipore; catalog no.: 07-1533), rabbit anti-H3K27me3/me2/me1 (Abclonal; catalog nos.: A2363, A2362, and A2361), rabbit anti-UTX (GeneTex; catalog no.: GTX12146), rabbit anti-eNOS (Cell Signaling Technology; catalog no.: 32027), rabbit anti-VE-cadherin (Santa Cruz; catalog no.: sc-28644), mouse anti-α-SMA (Sigma; catalog no.: A5228), goat anti-Hes1 (Santa Cruz; catalog no.: sc-13844), rabbit anti-PCNA (Santa Cruz; catalog no.: sc-7907), mouse anti-β-actin (GeneTex; catalog no.: GTX629630), and mouse anti-GAPDH (Santa Cruz; catalog no.: sc-32233).

Quantifying Differentiation in ALI Cultures

Differentiation was quantified in ALI cultures using previously reported methods and antibodies (70 (link)). Ciliated and goblet cell differentiation intermediates were defined as previously reported (36 (link)) and are illustrated in (Supplemental Figure 2).Three individuals, who were blind to the groups, used guide images to classify ciliated and goblet cell differentiation intermediates, and the 3 values were averaged. For analysis of cell surface markers, cultures were fixed with 10% neutral buffered formalin and blocked with 5% bovine serum albumin/1× PBS. Additional antibodies used in this study were as follows: mouse anti-JAG1 C-terminal–specific antibody (BD Biosciences, 612346, 1:50); rabbit anti-JAG2 N-terminal–specific antibody (Cell Signaling Technology [CST], C23D2, 1:50); rabbit anti-JAG2 C-terminal–specific antibody (CST, C83A8, 1:50); goat anti-HES1 (Santa Cruz Biotechnology, sc-13842, 1:40); rabbit anti-RBPJ (MilliporeSigma, AB5790, 1:100). Primary antibodies were detected with Alexa Fluor 488– or Alexa Fluor 594–labeled secondary antibodies (Jackson ImmunoResearch, 1:500). Nuclei were detected with DAPI.

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.
