The CTRB1 (Chymotrypsinogen B1) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CTRB1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CTRB1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human CTRB1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human CTRB1 in the samples is then determined by comparing the OD of the samples to the standard curve.

A Perfect Christmas Murder Cozy
Format: Kindle
Benedict Brown has succeeded again. It felt like going home for the holidays when Marius and Bella are together again. The story is great, the characters and suspects to murders have such varied and down-right strange manners that they are fascinating to get to know. The story is great. I didn’t guess “who done it”. Marius’ faithful dog, Bella’s faithful chauffeur, all met the new senior housing development residents dents where Bell’s dear Auntie was killed. Despite more murders to come, and despite ignorant or maybe just plain corrupt police, the cases are successfully solved in the end by Marius and Bella. Then a Merry Christmas indeed occurs with Marius , his Mom, Bella and other family. I love the way Benedict Brown always gives a synopsis of his research which is always unusual, informative and fascinating. I really enjoyed book. Well-done once again Mr. Benedict Brown. Keep up the good work.

I enjoyed getting to know Marius and Bella
Format: Kindle
This was the first book I have read the Marius Quin series by Benedict Brown. I do believe I would have enjoyed it more if I had more background into the primary characters, Marius Quin and Lady Bella Montague. However, I still liked spending time trying to solve the murder mysteries and getting to know Marius and Bella more. The relationship between the two of them is entertaining, and I loved that while they have such different personalities, their relationship is built on a lifelong friendship and full of warmth and caring. A nice cozy mystery that I enjoyed enough that I will go back and read the earlier books in the series.

Murder and Christmas Cheer!!!
Format: Kindle
Christmas is a joyous time of year and not a holiday usually associated with murder, but Benedict Brown serves up a classic British mystery, set in the 1920’s, with seasonal warmth, cheer and numerous deaths. This is the sixth novel in the Marius Quin series and, at the beginning of the novel, the reader finds Marius in a good place – he’s finally accepted that the war is over, his new novel is at his publisher’s and Bella, the woman he loves, is back in his life. At a Christmas party at Bella’s parents’ manor house, he runs into a white-haired lady, talking to herself. Adele Leach, “Aunt Addie,” says that she’d been to the police because a friend was in danger and, if anything happened to her friend, that she knows who her killer is, and then Adele rushes off. Quite soon thereafter, Adele is found dead and the police attribute her death to natural causes: She was in her 80’s and had a weak heart. Marius and Bella know better and go to Holly Village, where Adele lived, to investigate. Of course, more murder follows and the duo satisfyingly reveal the culprit, and the end of the novel is filled with Christmas cheer, reminiscent of A Christmas Carol by Dickens. The plot keeps the reader guessing, but what really appealed to me was the setting. Holly Village is right out of Dickens and is a real village which was built during the Victorian time, with twelve-dwellings, each with turrets, towers and gargoyles, located in the heart of London, next to Highgate Cemetery (an appropriate setting for a murder mystery)! I totally recommend this new Christmas novel by Benedict Brown.
