Item 1.

Security and Issuer.

	The name of the issuer is SomaLogic, Inc., a Delaware corporation (the "Issuer"). The address of the Issuer's principal executive offices is 2945 Wilderness Place, Boulder, CO 80301. This Schedule 13D amendment relates to the Issuer's Common Stock, $0.0001 par value per share (the "Shares").

Item 2.

Identity and Background.

	(a), (f)	This Schedule 13D is being filed jointly by CMLS Holdings II LLC, a Delaware limited liability company ("CMLS"), C-LSH II LLC, a Delaware limited liability company (“C-LSH”), M-LSH II LLC, a Delaware limited liability company (“M-LSH”), Casdin Capital, LLC, a Delaware limited liability company (“Casdin”), Casdin Partners Master Fund, L.P., a Cayman Islands exempted limited partnership (the “Fund”), Casdin Partners GP, LLC, a Delaware limited liability company (the “GP”), Eli Casdin, a United States citizen and Keith A. Meister, a United States citizen (collectively, the "Reporting Persons").

	(b)	The principal business address for each of CMLS, C-LSH, M-LSH and Keith A. Meister is 667 Madison Avenue, New York, New York 10065 and the principal business address for each of Casdin, the Fund, the GP and Eli Casdin is 1350 Avenue of the Americas, Suite 2600, New York, New York 10019.

	(c)	The Board of Managers of CMLS is comprised of Eli Casdin and Keith A. Meister. C-LSH and M-LSH are the members of CMLS Holdings II LLC and Eli Casdin and Keith A Meister are the managing members of C-LSH and M-LSH. Eli Casdin is the managing member of Casdin and the GP. The principal business of Casdin is serving as an investment adviser to its clients. The principal business of the GP is serving as the general partner to certain private funds. Casdin is the investment manager to the Fund and the GP is the general partner of the Fund. The principal business of the Fund is purchasing, holding and selling securities for investment purposes.

	(d), (e)	During the last five years, none of the Reporting Persons has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. The Reporting Persons disclaim membership in a group.

Item 3.	Source and Amount of Funds or Other Consideration.

	The funds for the purchase of the Shares came from the working capital of CMLS Holdings II LLC and from private investment funds managed by Casdin, including the Fund, over which the Reporting Persons, through their roles described above in Item 2(c), exercise investment discretion. No borrowed funds were used to purchase the Shares, other than borrowed funds used for working capital purposes in the ordinary course of business.

Item 4.	Purpose of Transaction.

	The Issuer entered into an Agreement and Plan of Merger on October 4, 2023 (the “Merger Agreement”) with Standard BioTools Inc., a Delaware corporation (“Standard BioTools”), and Martis Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Standard BioTools (“Merger Sub”). The Issuer’s stockholders adopted the Merger Agreement at a special meeting of stockholders held on January 4, 2024 (the “Special Meeting”). Pursuant to the terms of the Merger Agreement, on January 5, 2024, following the filing of a certificate of merger with the Secretary of the State of Delaware, Merger Sub merged with and into the Issuer, with the Issuer surviving as a wholly owned subsidiary of Standard BioTools (the “Merger”). Pursuant to the terms of the Merger Agreement, upon completion of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger was converted into the right to receive 1.11 (the “Exchange Ratio”) fully paid and non-assessable shares of common stock, par value $0.001 per share, of Standard BioTools (the “Standard BioTools Common Stock”), and cash in lieu of any fractional shares. In addition, as of the effective time of the Merger, Standard BioTools assumed each Issuer stock incentive plan, each outstanding option to Shares (the “Options”) and each outstanding restricted stock unit convertible into Shares (“RSUs,” and together with the Options, the “Equity Awards”), whether vested or unvested. Each such Equity Award assumed by Standard BioTools will continue to have, and be subject to, the same terms and conditions applicable to such Equity Award immediately prior to the effective time of the Merger, except that (A) such Option will be exercisable for that number of shares of Standard BioTools Common Stock equal to the number of Shares subject to such Option immediately prior to the effective time of the Merger multiplied by the Exchange Ratio and rounded down to the next nearest share of Standard BioTools Common Stock, (B) the exercise price per share will be the exercise price per share in effect for that Option immediately prior to the effective time of the Merger divided by the Exchange Ratio and rounded up to the next nearest cent and (C) such RSU will vest for that number of shares Standard BioTools Common Stock equal to the number of Shares subject to such RSU immediately prior to the effective time of the Merger multiplied by the Exchange Ratio and rounded to the next nearest share of Standard BioTools Common Stock. In addition, as of the effective time of the Merger, each Issuer warrant (“Warrants”) shall be treated in accordance with the terms of such warrant. The foregoing description of the Merger Agreement and the transactions contemplated thereby is qualified in its entirety by reference to the Merger Agreement, a copy of which is incorporated herein by reference to Exhibit 2.1 of the 8-K filed by the Issuer on January 5, 2024.

Item 5.	Interest in Securities of the Issuer.

	As of the Merger, the Reporting Persons were no longer deemed to beneficially own any Shares. The Reporting Persons have not effected any transactions in the Issuer’s Shares during the past 60 days other than as described herein. No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares beneficially owned by the Reporting Persons.

Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

	Not applicable.
