An OM worker from Latin America uses his carpentry skills to disciple young men in their faith and give them better employment opportunities for the future.

OM teams in five countries along the Mekong River in South East Asia are focusing on discipling local believers to see them equipped to share about Jesus with those who have never heard His name.

"Since my childhood, I have been anxious about missing out. I remember not wanting to sleep whenever I heard the adults chatting in the night. I wanted to be part of it all. Later on, in high school, I said “yes” to every event and outing, which ended up crashing so many times. I couldn’t choose. I wanted to be there to celebrate all the fun moments but also share all the tears in the low moments," says Ivy. "However, this lifestyle of being afraid of missing out could not continue when I joined missions. I have had to learn how to let go when I miss out on opportunities to create precious memories with family and friends in my home country."

God uses Janet to reach people through one-on-one encounters at a bookshop in a closed country.

The Main Hall session focused on wisdom, a word and concept used very much in everyday life. The truth is that God gives us wisdom, and He invites us to desire and search for it as we would search for treasure.

“Listening to their testimonies, I’ve begun to envision their stories as a collection of clues, a series of scenes revealing the fingerprints of something—or Someone—beyond our deepest imagination,” says Chris. “The people I talked with hail from a variety of backgrounds—atheist German to Cambodian Buddhist—but the tapestries of their lives reveal the same beautiful threads, pointing unmistakably to a Designer.“

Every year Washingtonians are treated to a feast for the eyes as ornamental cherry trees bloom across the city, most prominently by the Tidal Basin. As cherry blossom season approaches, we would like to share information about two related resources that we hope will offer some inspiration for those near and far: a selected set […]

Just across town from the Library of Congress in Washington, D.C., stands Gallaudet University, an institute for higher learning for the deaf and hard-of-hearing. In 1864, President Abraham Lincoln signed the law that allowed the school to begin issuing college degrees, a milestone for deaf people seeking higher education. Edward M. Gallaudet (right) was the […]

The only way to solubilize many antigens for immunoprecipitation is by denaturation. This cell lysis protocol is ideally suited for this purpose to release proteins from complex structures or reveal antibody epitopes hidden within native proteins. Short linear epitopes may not be accessible to antibodies within the native tertiary and quaternary protein structures, but they become exposed upon the unraveling of proteins, exposing their secondary structure. Antibodies otherwise not suitable for the immunoprecipitation of proteins prepared under nondenaturing conditions are now able to bind these antigens of interest in cell lysates prepared under denaturing conditions. These antibodies may also work well for immunoblotting purposes when the protein target is completely denatured. Harvested cells in this protocol are washed in tris-buffered saline (TBS) before lysis in 2% sodium dodecyl sulfate (SDS)-containing Lysis buffer for 10 min at 100°C. The resulting sample is diluted 20-fold in TBS to reduce the SDS concentration to ≤0.1% before the addition of an antibody for immunoprecipitation. Addition of 2% bovine serum albumin (BSA) or 0.1% Nonidet P-40 to the TBS before an immunoprecipitation, respectively, ensures either removal of SDS from the target protein or retaining denatured proteins in solution.

Differential detergent fractionation of cells is a rapid method for extraction of cytoplasmic and nuclear proteins in preparation of an immunoprecipitation. This method can be applied for use of adherent or suspension cells and can significantly reduce nonspecific background in an immunoprecipitation by separation of cellular compartments into individual fractions. The lysis of cells by differential detergents permits the rapid extraction of proteins from the cytoplasm (digitonin), the cytoplasmic membranes, and organelles (Triton X-100), and nucleoplasm (Tween/DOC), facilitated through the use of distinct extraction buffers. Cytoplasmic and nuclear matrix proteins as well as DNA are left behind during the detergent-based extraction.

This rapid and efficient method to prepare highly purified recombinant adeno-associated viruses (rAAVs) is based on binding of negatively charged rAAV capsids to an anion-exchange resin that is pH dependent.

This is a simple method for rapid preparation of recombinant adeno-associated virus (rAAV) stocks, which can be used for in vivo gene delivery. The purity of these vectors is considerably lower than that obtained by either CsCl gradient centrifugation or by combination of iodixanol gradient ultracentrifugation followed by column chromatography.

The most commonly used method for production of recombinant adeno-associated virus (rAAVs) in research laboratories is by transient triple transfection of 293 cells with AAV cis and trans plasmids and an adenovirus helper plasmid. This protocol describes the processes required to prepare the transfected cell suspension for virus purification.

Over many years, the Xenopus laevis embryo has provided a powerful model system to investigate how mechanical forces regulate cellular function. Here, we describe a system to apply reproducible tensile and compressive force to X. laevis animal cap tissue explants and to simultaneously assess cellular behavior using live confocal imaging.

In this protocol, DNA fragments are separated according to size by electrophoresis through low-melting-temperature agarose, and then recovered by melting the agarose and extracting with phenol:chloroform. The protocol works best for DNA fragments ranging in size from 0.5 to 5.0 kb. Yields of DNA fragments outside this range are usually lower, but often are sufficient for many purposes.

Mice, rats, or hamsters are immunized by giving biweekly injections of a purified antigen, cultured cells, or cDNA. For mice, if a pure, soluble protein antigen is being used and is abundant, a dose of 50–100 µg in adjuvant at each immunization is a sensible general recommendation; for rats and hamsters, a dose of 100–200 µg is sufficient. Lower doses can be used for antigens with higher immunogenicity. Adjuvants (Freund's, Ribi, Hunter's TiterMax, ImmunEasy, or Alum) should be mixed with the immunizing antigen for the first two immunizations only; Complete Freund's adjuvant is only used with the first immunization. Subsequent immunizations are performed in phosphate-buffered saline (PBS) or normal saline, with or without Incomplete Freund's adjuvant. The choice of adjuvant is dependent on the subclass of immunoglobulin required. Over the course of the 6-wk immunization schedule, each animal usually receives a total of six injections (three subcutaneous and three intraperitoneal). Once a good titer has developed against the antigen of interest, regular boosts and bleeds are performed to collect the maximum amount of serum. For rats and hamsters, boosts should be spaced every 2–3 wk, and serum samples of 400–500 µL should be collected 10–12 d after each boost. For mice, boosts should be spaced every 2–3 wk, and serum samples of 200–300 µL should be collected 10–12 d after each boost.
