Background

The assay kit utilizes homogeneous time-resolved fluorescence (TR-FRET) technology to measure the interaction between PD1 and PD-L1. This method enables simple, rapid, and high-throughput screening of inhibitors and antibody blockers.

As shown in the figure, the interaction between PD1 and PD-L1 is detected using an Eu-labeled anti-Tag1 antibody (TR-FRET donor) and an Ac-labeled anti-Tag2 antibody (TR-FRET acceptor). The binding of PD1 and PD-L1 brings the donor and acceptor antibodies into proximity, allowing the excitation of the donor antibody to trigger fluorescence resonance energy transfer (FRET) to the acceptor antibody, resulting in a specific emission signal at 665 nm. Pembrolizumab, as a positive control, blocks the interaction between PD1 and PD-L1, preventing FRET signal generation. The stronger the blocking effect of the screened drug on the PD1/PD-L1 interaction, the lower the signal. The specific signal is proportional to the extent of the PD1/PD-L1 interaction. This homogeneous assay is simple to perform and requires no washing steps.

Fallen Angels, fae, vampires, oh my!
Format: Kindle
Rating: 4.5 | Spice: 2 (but a good slow-burn) • Main Characters: Huntyr and Wolf • I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆 We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger! • Emily, thank you for writing this awesome novel and I cannot wait to devour Book 2, Blood So Brutal! 😍 • Happy reading, my lovelies! xo

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️ I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well. Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on. Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc? However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy. Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book. Overall ratings: Plot- 3.5⭐️ World building 3⭐️ Spice 2.5 🌶🌶 Main characters 4 ⭐️ Supporting characters 3.5⭐️

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book. I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.

Fallen for the Fallen Angel – A Guilty Pleasure Worth Every Page
Format: Kindle
There’s something deeply irresistible about a dark academia or trial-based setting, a brooding and arrogant fallen angel, and a fierce heroine with enough sass to go toe-to-toe with him. Wings So Wicked is exactly that kind of book—and I devoured it in just a couple of days. To be fair, the plot isn’t groundbreaking. If you’re looking for something fresh and innovative in terms of storyline, this might not be it. But if your reader heart beats faster at the mere mention of enemies-to-lovers, jealousy-fueled banter, magical trials, betrayals, and forbidden tension—you’ll feel right at home. It’s like catnip for those of us with this particular weakness. The chemistry between the leads could have used a slightly slower burn to make the tension sizzle longer, but I still found myself completely invested in their dynamic. There are moments and phrases that feel a bit cheesy or underdeveloped, but honestly? I didn’t care. The vibes were exactly what I wanted. This book isn’t trying to reinvent the genre—it’s here to give readers like me what we crave: high-stakes magical drama, angsty romance, and the thrill of watching a badass girl and her brooding counterpart clash and spark. If that sounds like your kind of story, Wings So Wicked will hit the mark. Here’s hoping Book 2 turns up the heat and keeps the magic alive.
