For protein-level quantification, ELISA and western blotting remain widely used. Q3. What are the challenges of working with recombinant CCR1 protein? ...
Recombinant MGP is typically purified using affinity chromatography and validated by SDS-PAGE, Western blot, and mass spectrometry to confirm integrity and modification status. ...
Additionally, the expression levels of core pluripotency transcription factors, including Oct4, Nanog, and Sox2, are quantified using techniques like quantitative PCR and Western blotting. The presence of these markers confirms that the iPSCs maintain their pluripotent characteristics. ...
Analytical techniques such as SDS-PAGE, Western blotting, and mass spectrometry are often utilized during this stage. Applications of Recombinant Proteins Recombinant proteins produced in CHO cells have myriad applications across various fields. ...
Techniques such as ELISA, surface plasmon resonance, and Western blotting are commonly used to evaluate these parameters. 5. Expression and Purification Promising candidates are expressed in a suitable host system. ...
Additionally, two-dimensional electrophoresis and Western blotting are frequently used to study differential protein expression.Quantification MethodsLabel-based or label-free quantification strategies can be used to quantify the abundance of proteins in different samples, determining which proteins are differentially expressed.Biological SignificanceDifferentially expressed ...
ImmunoprecipitationThis uses phosphorylation-specific antibodies to precipitate phosphorylated proteins, followed by detection through western blot or mass spectrometry analysis.4. Phosphatase TreatmentThis treats protein samples with a phosphatase to determine the phosphorylation state of protein by comparing the phosphorylation levels before and after treatment.5. ...
Compared with ELISA and Western blotting, it offers higher specificity and coverage.Multiplex Immunoassay TechniquesFor example, using platforms based on multiple antibodies, multiple HCPs can be detected simultaneously.When conducting host cell protein (HCP) residual detection, it is essential to consider the specific host system used for the production of bioproducts, as ...
ImmunoblottingSuch as western blotting, it's suitable for detecting specific, potentially high-risk HCPs.4. ...
These forms of glycosylation affect protein folding, stability, and distribution.Methods and Techniques for Glycosylation Site DetectionTraditional glycosylation site detection methods include mass spectrometry analysis and Western blotting. Mass spectrometry can accurately identify glycosylation sites, while Western blotting is used to detect the glycosylation ...
Immunological MethodsUsing specific antibodies (such as antibodies against specific glycated collagen) for ELISA (enzyme-linked immunosorbent assay) or Western Blot can detect and quantify specific glycated collagen.4. Biochemical AnalysisUse specific chemical reagents (such as certain compounds that can specifically bind to glycation sites) to quantify the degree of collagen ...
For instance, the acetylation state of histones directly influences chromatin structure and the regulation of gene expression.Acetylation detection usually relies on specific antibodies and can identify and quantify acetylated proteins through techniques such as Western blotting, immunofluorescence, or Mass Spectrometry. These methods provide high specificity and sensitivity and ...
Ubiquitination DetectionThe eluted protein is subjected to SDS-PAGE electrophoresis, followed by Western blotting. Anti-ubiquitin antibody is used for detection.After carrying out immunoprecipitation and ubiquitination detection, we can analyze the results. ...
This epitope might show high similarity or significant differences in sequence across different species.From a purely practical perspective, compared to other forms of antigens, the synthesis of peptides also has the advantages of being simple, fast, and inexpensive.The Key to Designing the Right PeptidesPeptides have long been the preferred antigen for antibody development in ...
The overall workflow of Far-Western Blot technology is similar to Western Blot, but the detection of target proteins in Western Blot requires antibodies, while antibodies are not needed in Far-Western Blot analysis. Instead, purified and labeled "bait" proteins are used to detect and assay the target proteins on the membrane. In ...
To detect protein ubiquitination, methods such as Immunoprecipitation (IP) combined with Western blot, mass spectrometry analysis, etc., are commonly used. Here are the typical steps for protein ubiquitination IP.Analysis Workflow1. ...
Linear epitopes are suitable for use in protein blotting (Western Blot) and paraffin-embedded immunohistochemistry experiments, and native epitopes are more suitable for immunoprecipitation (IP), cryosection immunohistology, flow cytometry, and enzyme-linked immunosorbent assay (ELISA). ...
Detection of Protein Expression LevelsThrough techniques such as Western blot or immunofluorescence, the expression level of the target protein after gene knockout can be detected, which is also an important method to evaluate the efficiency of gene knockout.3. ...
Immunoblot AnalysisPerform immunoblotting (Western Blot) analysis using antibodies against ubiquitin to detect whether Tau protein is ubiquitinated.5. ...
Analysis of Washed SamplesElute proteins from the solid material, and then analyze the proteins using methods such as SDS-PAGE or Western blotting. You can use specific antibodies to check for the presence of your ubiquitinated target protein, and to see if ubiquitin proteins co-precipitated with it.6. Result InterpretationBy observing the results of the Western ...
