Rabbit anti gfp alexa 488

Manufactured by Thermo Fisher Scientific

Rabbit anti-GFP Alexa-488 is a primary antibody that specifically binds to green fluorescent protein (GFP). It is conjugated with the Alexa Fluor 488 fluorescent dye, which emits green fluorescence when excited by the appropriate wavelength of light. This antibody can be used for detection and localization of GFP-tagged proteins in various biological applications.

Phospho-p44/42 MAPK Localization in Stab2 Morphant Embryos

Check if the same lab product or an alternative is used in the 5 most similar protocols
Control uninjected and Stab2 morphant embryos were fixed in 4% paraformaldehyde (PFA) at the 20 somite stage, dehydrated in ethanol and stored at −20°C. Embryos were rehydrated and blocked in blocking reagent (Roche). Following blocking, embryos were incubated in rabbit polyclonal anti-phospho-p44/42 MAP kinase antibody (Cell Signaling Technologies) overnight, washed, incubated in rabbit anti-Alexa647 (Invitrogen) for four hours, washed, and incubated in rabbit anti-GFP Alexa-488 (Invitrogen) overnight. Embryos were analyzed and imaged using fluorescent microscopy.

Antibody Staining Protocol for Confocal Microscopy

Check if the same lab product or an alternative is used in the 5 most similar protocols
Detailed protocols for antibody staining have been published previously (Lorent et al., 2004 (link)). Primary antibodies included rabbit anti-GFP-Alexa 488 (1:400, except 1:200 following fluorescence in situ hybridization) (Invitrogen), rabbit anti-Mdr (1:100, Santa Cruz Biotechnology), and mouse monoclonal 2F11 (1:1000, gift of Julien Lewis). Primary antibody incubations were performed overnight at 4°C. Secondary antibodies included goat anti-rabbit IgG-Alexa 568 and goat anti-mouse IgG-Alexa 568 (Invitrogen), and were diluted 1:600 for incubation at room temperature for 2–3 h. For confocal microscopy, livers and attached gastrointestinal tracts were dissected from immunostained larvae and mounted in Vectashield with DAPI (Vector Industries), coverslipped, and imaged using a Zeiss LSM 700 confocal microscope.

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.
