Chicken SAA SPARCL™ kit – added August 18, 2021
The chicken serum amyloid A (SAA) SPARCL™ kit (SAA-SP-5) is a 96-well luminescence assay that allows quick and easy measurement of SAA in chicken plasma. Samples (50 μl) and conjugate mixture (25 μl) are co-incubated for 30 minutes in wells of a SPARCL™ microtiter plate. The plate is then inserted into a luminometer and luminescence is measured after injection of trigger solution (37.5 μl/well). A wash-step is not required. SAA concentrations in the samples are derived from a standard curve. SAA is a good inflammatory biomarker in chickens; its levels can increase >50-fold. Pricing information and a list of our other SPARCL™ kits can be found on our SPARCL™ kits page.

Elephant SAA ELISA – added August 17, 2021
At the request of one of our customers, we developed an ELISA kit for elephant serum amyloid A (SAA-22). The assay recognizes Indian elephant SAA. We expect it to recognize African elephant SAA too. SAA is an acute phase protein. Serum levels increase during inflammation and disease. The kit can therefore be used to monitor elephant health. Pricing can be found on our acute phase protein ELISA kits page.

The new kit (CRP-10-N) uses rabbit CRP IgY antibodies that were generated by injecting chickens with pure rabbit CRP and affinity purified on rabbit-CRP agarose. The standard used in the kit was calibrated to pure rabbit CRP, the concentration of which was determined by absorbance at 280 nm using the known extinction coefficient. Kit CRP-10 will be discontinued when antibodies used in its production are exhausted. Please refer to the kit instructions for more details.

Human Anti-PEG IgM ELISA – added February 15, 2021
The human anti-PEG IgM ELISA (PEGM-20) measures levels of anti-PEG IgM in serum, plasma, and other fluids.

Dog Pancreatitis Associated Protein-1 (PAP-1) ELISA – added July 21, 2020
PAP-1 is an acute phase protein. Its expression is very low in healthy pancreatic tissue but increases significantly during acute pancreatitis and other diseases. In studies at LDI, we found that fecal levels of PAP-1 increased significantly in dogs with IBD. The dog PAP-1 ELISA (PAP1-4) uses dog PAP-1 specific antibodies developed at LDI and is calibrated to pure dog PAP-1. It can be used for the measurement of PAP-1 in fecal extracts, serum, and plasma (other fluids have not yet been tested). A single 96-well kit is priced at $550. Volume discounts apply.

Anti-Cow Haptoglobin Monoclonal Antibody – added March 19, 2020
We have recently added another cow haptoglobin monoclonal to our catalog. HAPT-11-6A8 pairs with HAPT-11-3F7 in SPARCL™ assays. Its performance in ELISA is being investigated. Call or email for pricing.

Horse CRP – added February 17, 2020
We now manufacture horse CRP (8108). CRP is an acute phase protein. Its levels increase during bacterial infections and inflmmatory conditions. It is available as 0.1 mg ($320) and 1 mg ($1600) quantities.

Cow SAA3 ELISA – added December 31, 2019
SAA3 is the isoform of serum amyloid A that is present in milk. It is sometimes referred to as milk amyoid A (MAA). Levels increase because of inflammation and infection associated with mastitis. As shown in the graph below, we find that SAA3 levels correlate with somatic cell count (SCC). Increased SCC correlate with decreased milk quality. The cow SAA3 ELISA (SAA3-11) was developed by Veterinary Biomarkers, Inc. It is simpler, faster, more sensitive (5x), and less expensive than other SAA3 ELISA kits. A single kit costs $450. Bulk discounts apply.
