Thanks, David. Hello, everybody.
Let's go ahead and start and move to Slide 3 of the presentation, take a look at the highlights for the quarter. Well, as expected, we had a tough start to the year. However, I will say that, with strong gross margins combined with previously communicated cost reductions, it positioned us to underpin our commercial investments for growth while at the same time meeting our earnings targets. Also as expected, significantly slower sales in China and Asia Pacific continued through Q1, further exacerbated by some slowing in Europe and in total a tough comparison to a record-high prior year Q1. I'll also mention we're still seeing some supply chain issues. As an example, Q1 saw one product alone that had $1 million in revenue shipment delays pushing it out of Q1.
So now let's go ahead and look at the numbers. Revenue in the quarter came in at $24.5 million, down $5.5 million from last year. Gross margin remained strong at 60.3%. On a GAAP basis, we recorded an operating loss of $2.3 million. On an adjusted basis, operating profit measured $1.2 million or 4.8% of revenue. And adjusted EBITDA measured $1.6 million or 6.6% of revenue.
Let's move to Slide 4, look at the revenue by the -- for the quarter by product family and looking at the regions.
So starting with the Americas. Revenue was down 6.6% as reported. Preclinical revenue was slow on reduced demand of COVID-related respiratory products. Cellular and molecular products were up modestly in advanced -- primarily with the advanced cell-based testing systems.
We saw slow sales in academic research, with NIH grants that seem to be taking longer to approve, but we believe much of that is due to the uncertainty that was around the congressional continuing resolution situation last quarter. We're hopeful that the more recent longer budget resolution will start to solve some of this for us. Pharma and CROs are still keeping tight strings on spending, but we're encouraged to see biotech-related capital raises improving. Biotechs, we see, represent a potential long-term tailwind for our technologies.
Moving on to Europe. Overall EMEA revenue was down 16% as reported, and that includes about a 1% currency headwind. Preclinical systems were down on tight budgets for both pharma and CRO companies. Cellular and molecular saw some slowness on tight government spending for academic research. The European economic environment is being impacted by the higher interest rates. And government spending also was hit by the situation that's occurring in Ukraine.
Now moving to China and Asia Pacific. Q1 reported revenue was down 35% on continued slower spend levels, which should annualize in the second half of this year. Preclinical revenue was down on continued slow capital equipment spending by pharma and CRO companies. Cellular and molecular products saw continued headwinds as academic customers awaited news on government academic research funding. We see the weakness in China continuing into Q2, though we're hopeful that the recent announced Chinese stimulus package will lead to improved market conditions entering the second half for us here.
Let's move to Slide 5 and discuss some new product launches designed to strengthen our base business while at the same time investing in new high-growth opportunities. Our commercialization focus started with new product introductions showcased at the latest Society for Neuroscience and the society for toxicology. Our primary focus is to strengthen our bread-and-butter base business which represents nearly 85% of total revenue and which we target to deliver better-than-market growth.
We invest to continue our leadership position in telemetry for safety and toxicology applications. We introduced our new SoHo shared housing telemetry family of implantables to expand our offering to multi-animal shared housing environments. At the same time, we introduced our latest Ponemah software that integrates VivaMARS, the high-capacity behavior testing system, onto a single GLP-compliant data system. Adding high-capacity neuropharmacology testing expands our addressable market by expanding the test menu offering to neuropharmacology and builds on our base business.
The Ponemah platform, which is used by the leading CROs, biopharma and large academic institutions around the world, processes and manages extremely large data pools acquired during tox and safety testing, now for both telemetry and now for behavior. By combining these new applications on a single data management platform, the Ponemah system opens up opportunities to use emerging AI and machine learning technologies to analyze study data.
At the same time, we continue to fortify our leading position in cellular, molecular and inhalation technologies for research and discovery. And also at the same time, we're expanding our field service offerings designed to increase recurring revenue and consumables. This year, we're driving to commercialize exciting, new high-growth opportunities. Electroporation and amino acid-related products make up around 10% of our revenue, and advanced microelectrode array products about 5%. Bioproduction and organoids provide exciting, new opportunities for high growth well above our base business. As such, we've established commercial and application science team dedicated to bioproduction and to advance cellular applications with emerging organoids. We're now offering bioproduction configurations of our well-known BTX family of electroporation and electrofusion systems. Bioproduction is an opportunity to drive significant recurring consumable revenue for us.
We recently also announced a cGMP-compliant amino acid analyzer also now targeted for bioproduction applications. This AAA system is adapted from our clinical amino acid systems which is in operation today in leading clinical laboratories around the world.
Finally, we're leveraging our historical leadership position in advanced cellular applications to drive high volume growth in both biopharma and CRO. We launched the Mesh MEA organoid platform at the Society for Neuroscience. We also showcased mesh organoid at the society for toxicology, where we see a potential for in vitro neuro and cardiac safety and toxicology applications. We're excited to see strong interest for applications in research and biopharma discovery, which we expect to then lead to high-volume compound analysis and testing applications.
Now I'll turn the call over to Jennifer, our CFO, to take a look at the key financials.
