Chicken anti insulin

Manufactured by Abcam
Sourced in United States

Chicken anti-insulin is a primary antibody that recognizes insulin, a hormone produced by the pancreas that regulates blood sugar levels. This antibody can be used in various immunoassay techniques to detect and quantify insulin in biological samples.

Immunofluorescence was carried out as previously described [17 (link)] using commercial antisera against glucagon (guinea pig anti-glucagon at 1:7000; EMD Millipore, Billerica MA), somatostatin (sheep anti-somatostatin at 1:1000; American Research Products Inc., Waltham MA), insulin (chicken anti-insulin at 1:1000; Abcam) and IL1r1/CD121a (armenian hamster anti-mouse Il1r1/CD121a-APC at 1:100; Biolegend, San Diego, CA). Rabbit antisera against UCN3 (#7218, 1:2000) and CRH (rc70, 1:5000) were generated in house. Secondary antibodies were raised in donkey against each of these host species and were obtained from Jackson Immuno Research Laboratories (West Grove, PA) conjugated to Alexa Fluor-405, -488, -649 or Cy3 and used at 1:600. Dapi was applied as a nuclear stain at 1 microgram/ml and slides were embedded with Prolong Gold antifade reagent (Life Technologies, Carlsbad, CA). All imaging was carried out on Zeiss LSM780 confocal microscopes at The Waitt Advanced Biophotonics Center Core facility of the Salk Institute.

Immunohistochemical Evaluation of Pancreatic Islets

Immunohistochemistry was performed for the observation of GFP-expressing cells, as described previously [14 (link)]. The primary antibodies used in this study were the following: guinea pig anti-insulin (1:1000; Dako, Carpinteria, CA, USA), chicken anti-insulin (1:1000; Abcam, Cambridge, MA, USA), rabbit anti-GFP (1:200; MBL, Nagoya, Japan), and anti-Ki67 (1:100; BD Pharmingen, Franklin Lakes, NJ, USA). Insulin-positive area and total pancreas area were measured using a BZ-X analyzer (Keyence, Osaka, Japan), and β-cell mass was calculated as relative β-cell area multiplied by the pancreatic weight. For the detection of Ki67, mounted sections were microwaved at 95 °C for 20 min in citrate buffer (pH 6.0) for antigen retrieval, before being incubated with blocking serum. Slides were observed using an Olympus FV1000D confocal laser-scanning microscope. In order to detect apoptotic cells, TUNEL assay was performed using an apoptotic detection system (Merck Millipore, Darmstadt, Germany) according to the manufacturer’s protocol.

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.
